Title: Falk Locomotive build
Post by: bparrish on March 19, 2014, 01:46:33 AM
John Siekirk put me up to this so here we go.

I started on the notion of building a G scale locomotive late last fall while on an anti rejection drug after I received a blood stem cell transplant.  The drug gave me something that could only be described as the permanent coffee jitters.  So I had to give up HO for a time and move to something a little larger.

I had long been fascinated with this locomotive and considered building this in HO but there was no place to put a motor and even in G scale it's going to be tight.

The plans are from an Al Armitage article in the Mar/Apr 1988 issue of Narrow Gauge Gazette.

The only parts I have used from a commercial source are the wheels that I obtained from Allan Pollock at Missouri Locomotive Company.  Beyond that everything is bar stock from a local metal supply house here in Boise.

The scaling of the locomotive drawings from the prototype to something that could be built took about two months as simply scaling something down doesn't mean it can be modeled with enough durability to hold together while operating.

I made the decision early that I would make the valves operate in time with the main rods and cylinders and that the brakes, although out of the way for running the locomotive, could be engaged manually.

With that........... I begin.

Below is a photo of the main frame rails with nothing but the wheels loosely installed.

And then with the end beams on so as to set the spacing of the frame rails.  Everything relies on this calculation.
(http://modelersforum.com/gallery/81-180314134307.jpeg) (http://modelersforum.com/gallery/81-180314134307.jpeg)

I also decided that the suspension would be sprung so I created a spring system as it showed in the drawings.

Also shown above is the retainer plates for the axles

I'll stop for now and add some more tomorrow.  All of these photos are resident on this site in the gallery.

Next batch..........

It should be noted at this point that all of this is just so many parts as it will all need to come apart and have each part cleaned, rounded and shaped, and a final finish put on.  Finishing includes working out with 400 grit emery paper.  I shared an office when I was in the school district with an auto body instructor that had a huge sign on the wall that said, "don't sand metal".  I understand why that is important in auto body stuff but I can't just leave stuff raggedy and hide it with paint.

Steam chests and cross heads are next.  The steam chests are a turning for the cylinder heads and soldered to some 5/8" brass tubing.  The fun part of this is being able to make up parts that can't be modeled in HO.  The packing glands for where the piston rod comes out of the piston is a fun part to make.  I'm going through a lot of 00-90 nuts and bolts.

(http://modelersforum.com/gallery/81-180314134755.jpeg)

The cross head beam is steel as it won't hold paint during operation. 
(http://modelersforum.com/gallery/81-180314134833.jpeg)

The oilers on the top of the valve box are a simulation of the Lunkerheimer oilers.  The prototype have a glass sight for how much oil remains in it and another of watching the drip.  The oilers are fully adjustable for how many drips per minute.  They have a shut off but along with everything else on a steam locomotive, operations were a very labor intensive.  I have a prototype of this oiler if anyone wants to see what one looks like.

The cross head slider mechanism is a third generation part as it took me several before I liked the appearance and worked acceptably; as in, little or no friction with no oil.
(http://modelersforum.com/gallery/81-180314134905.jpeg)

(http://modelersforum.com/gallery/81-180314134933.jpeg)


Next are the Gooch links.  I think the name comes from the inventor and date to the mid nineteenth century.  This sort of valve linkage replaced D hooks and some other early linkages that required full stops to change direction.  Although shifting from forward to reverse on the fly was tough on machinery it also allowed for something of a neutral.  The link rocked from a motion at an axle cam and the link was raised or lowered from a central point to accomplish forward or reverse.  This link survived for a very long time and is visible in a modified form on the Walshaerts valve gear.  The improvement was that the Walshaerts was all outboard of the frame and could be oiled and adjusted more easily.  Baker and Southern valve gears all work similarly but the Gooch link is modified and less noticeable.

Coupla things........

Here is a shot of the now ancient Unimat that I use for making this whole thing up.  I've had this lathe since about 1962 and have built a lot of stuff from it.  There was nothing available in small scale machine tools at the time as there is now.
(http://modelersforum.com/gallery/81-190314213429.jpeg)



Next is a photo of the cab sides with the lower panels done and the stationary window in place.  As sliding window will be in a movable track behind this and both will have real glass in them.  I have this thing about nothing looks like glass except glass.  The mullion for the glass is visible.  I use microscope slides for glass.

Well with those flattering remarks.......... I'll put up the rest of the photos and get caught up.  These photos were elsewhere on several threads and that's why John suggested I pull 'em together.

I have also figured out how to pull in photos and text...... with John's help.

The valve linkage is designed to operate and demonstrate how an early Stevenson system worked.
First is the Gooch links fastened to the hangers. As the link is constantly rocking when the locomotive is moving the hanger is needed to get rid of the transfer of motion to the selecting apparatus.
(http://modelersforum.com/gallery/81-180314135047.jpeg)

This photo shows the selecting apparatus before mounting to the frame rails.
(http://modelersforum.com/gallery/81-180314135113.jpeg)

The next photo show the entire linkage mounted in the frame and secured to the valve levers.
(http://modelersforum.com/gallery/81-180314135140.jpeg)


The following two photos show the Valve levers and the valve rods to the steam chests.
(http://modelersforum.com/gallery/81-180314135422.jpeg)

The valve rod is clevised to a piece of .062 ID brass tubing and is threaded to 00-90.  The screw comes from the inboard of the valve lever and collides with the valve rod to secure it.  The screw is cut just long enough to allow it to float freely in the valve lever as it rocks during operation.
Valve rod is visible at left center.

Title: Re: Falk Locomotive build
Post by: bparrish on March 20, 2014, 01:54:21 AM
Next is the operating mechanism for the Gooch links.

This was accomplished with a series of cams that were mounted on an axle in between the frame rails.  This was the major draw back of the Stevenson system as it was high maintenance and difficult to get to.

This shows the two cams before I split them to create a clam shell that would clamp to the axle to allow the valves to be timed to the motion of the pistons.  This timing is also correct in reverse.
(http://modelersforum.com/gallery/81-180314135259.jpeg)


Cams have peen split, had set screws applied and mounted to the axle.
(http://modelersforum.com/gallery/81-180314135338.jpeg)

The four connecting rod big ends are shown here before splitting to create a rod and cap; very much like an automobile engine.  On the prototype these were of a poured in babblt bearing that was high maintenance also.
These were turned out of a piece of 9/16 brass rod and bored to a few thousandths smaller that the cam diameters.
(http://modelersforum.com/gallery/81-180314135530.jpeg)

A finished rod big end that was split, drilled and threaded for 00-90 screws. Then put back in a four jaw chuck and counter bored for final fit to the cam as splitting the part caused the hole to be .010" out of round due to the thickness of my saw blade.
(http://modelersforum.com/gallery/81-180314135558.jpeg)

Title: Re: Falk Locomotive build
Post by: bparrish on March 21, 2014, 08:50:50 PM
So I met with disaster today........

I clamped up the two sides for the cab with the cross members to start framing it up, along with some temporary pieces to stiffen the structure a bit as there is not much there.  When I took it out of the clamps today in fell apart with only a small amount of handling.

To keep the scale there isn't much there in the mortise and tenon structures at the corners.......

So with that...... the wood is hereby abandoned and I'm going to build the cab in brass.  I've got it re-scaled and will start tomorrow.

I'll put up something when I have something.

Sorry, I don't have any experience with gluing wood to brass. How are the wood cabs attached in the 1:1 world - bolts, rivets? I will see if I have any pictures - never thought about it?

Post by: bparrish on March 22, 2014, 02:06:32 PM
John...

Wood parts were bolted to steel bracketing.  Typically there might be some "L" bracket that was held to the wood with carriage bolts and then bolted to the larger structure with cap bolts and nuts.

Corner reinforcing was also done with "L" brackets and carriage bolts.

My plan was to drill into the bottom boards of the cab with relatively large holes and fill them with CA glue.  Then position and mark for machine screws.  Then drill into the cured CA and hang 00-90 or 0-80 machine screws.  CA actually takes threads rather well............  That was how I was going to bolt the cab to the deck that is already done.

So I'll lay it out and do it in brass.  It was always sort of a back up plan if the wood didn't work.

If I had to glue wood to brass, I'd use either epoxy or a contact cement.  For a relatively large lamination operation, I'd think about Walthers Goo, since that remains flexible long-term.  But I haven't actually done something the size of your cab.

James and all.....

I've never built anything this big either.  I can't believe how easy it is to quarter drives in G scale.  You only have to be close and it likes it.  HO is a bear.

I'm working on using brass.  I have the layout and the first side is part way done.  A lot of hand filing and measuring.

So here is the first of the cab sides in brass.  Hard to believe that the lay out and fitting was about ten hours. The second one won't be so long.

It's also amazing how much distortion - fish eye occurs when taking something close up.  Nothing looks square!!

Still needs polished out and the windows fitted.

Got both cab sides done.  The second took half the time of the first.  I cheated......  I traced the first onto the second so the layout time was only a few minutes compared to an hour or more.

Now on to the cab front, which has to be made in two sections; the upper with windows and the lowers as they need to be removable from the larger cab for assembly purposes.

Got the cab front done this morning.  The lower section below the windows will need to be built separately and fastened to the cab base as there are controls that go out onto the frame and boiler.  I'll try and get the main parts of the cab soldered up this afternoon.

Got the window frames in the slider tracks but again, glass goes last.

Still needs a bunch of cleaning.

So I had way too much fun with this today.

Here is the boiler and steam dome.  The boiler is two wraps of sheet brass.  The smoke box is .003" and rivets punched in.  The main boiler is .006" brass that represents the lagged portion of the boiler.

Yes.... you guessed it........ the white plastic core piece is  a PVC pipe coupling that only needed about .015" turned off to come to the correct core diameter.  Surprisingly, the PVC actually takes holes and threads rather well so the remaining bolt on stuff will be easy. 

The dome is two parts and the top was set up on an indexing table to drill the 00-90 bolt holes.  The top is actually press fit into the dome side piece and the bolts are purely cosmetic.

I'll get after the various lagging straps tomorrow.

Hal...

I'm not sure about special orders.  At the rate I'm going...... at a buck and hour you still couldn't afford me.

Some of this stuff I'm painfully slow at and other stuff comes in on the first try.  On the dome top photo that I most recently put up............ I hadn't used an indexing table in nearly twenty years.  Most stuff in HO just doesn't need to be that precise.  G and F scale is all different.  This is my first foray at such a large scale.

I got the stack base done and the hold down devices done for the dome and stack base.  I'll get the line up for that done yet today.  The boiler front is also done but not soldered on yet as I need to bolt down the stack and dome first.  It really matters that straight up on all of this is really straight up.

Thanx'

OK.................

It doesn't seem possible that it took two days to get the firebox and back head built.  I've never made a compound curve on a sheet brass panel before.  I procrastinated on the back head from the very beginning for that reason.

I had too much fun making up the valves and the sight glass.  I found a piece of optical fiber that measures out at .024 which comes out at something over a half inch in G scale. I still have a bunch of fitting and cleaning.

Lower cab front panels are next.  These had to be separate as they are mounted to the base plate so that the cab is easily removable.

I had to scale the fire box a little tall so as to get the motor in.  Never I thought I would struggle for space in G scale.

Today was a good day.  Got the throttle stand done and mounted with an improved sprint system over what I posted in a photo yesterday.

Also finished the Johnson rod.

Who's this Johnson guy...... anyway ? ? ? ?

As shown.......... throttle lever is off and the valve linkage is set to neutral.

I'm having way too much fun with this......

So I have been at it but not much shows until now.

The lower cab fronts are in and the cab is bolted to the deck.  Those lower panels needed to be separate from the cab as there are control rods on the side showing and the single cylinder gypsy engine on the other side.  This took a time to get sorted out.

The dry pipe is into the steam dome.  Straight up is the pressure regulating valve and out of the side is the whistle.  Below is the main shut off valve and below is a flange coupling.  At the bottom is an elbow and in front of that will be another valve that is the actual throttle valve.

This locomotive was so primitive that much of this would have never be seen as it would have been inside the boiler or at least hidden by the lagging.

More tomorrow

Title: Re: Falk Locomotive build

More small parts today.

I put on the second companion flange.  These parts were necessary as they had to be able to remove and service the various valves on the pipe.  Sort of like a union on household plumbing.   These are nothing more than two washers and short bits of sleeve tubing.  Maybe I shouldn't tell you how easy some of this stuff really is to make.

The throttle valve is different than a globe or gate valve.  As the valve only has a quarter turn from off to full, there can only be a gas type valve in there.  They were tapered inside the housing to compensate for wear and a shaft came out the back side to a spring to keep it loaded.  The spring is out of a Central Valley passenger truck frame.  The throttle lever is free to turn.

The various pipe fittings are layers of stacked tube and flooded with solder and shape to look like castings.

True confessions ..........

Earlier today I managed to mix up two 00-90 screws that went into blind holes of different depths and broke the long one off in the short hole..............

Now......... Just for the record.......... I hate Norm Abrams.........you know .....the wood worker guy.

If any of you boys back east know him .......... please don't forward this to him....

He never measures anything twice......... He never cuts a board too long........ and he NEVER cuts a board too short.

And everything goes together the first time and he never says Opps .....or worse...........

I've never been able to work consistently like that..

So tonight ..... late .... this broken screw was eating me Soooooooooo bad that I had to go up to the RR room and dig out that screw.  I successfully dug out a 00-90 screw and was able to use the existing threads.

So tomorrow I'm back at it without further delay.

So I finished the lower stack today...... Leaving town for a while so no progress for another week.

Still need to build the screen catcher over the top.  I have an idea for a hinged mechanism so it will operate.

Working in G scale is fun because you can make all of this work. Can't do that in HO.  Outside Walshearts valve gear is about as small as I can go in that scale.

Thank you for your very nice remarks.  I just got back from a week long follow up doctor thing in Seattle so I'm back at it.  Next objective is the gypsy engine on the fireman side of the loco.  I am really procrastinating on the wood box and water tank.  "lots o rivets".

So I got the combined water tank and wood box at least mounted on the frame today.

Took a day of layouts and then a bunch of time pounding out rivets.   I have  ton of detail stuff to add: water inlet, water drain, box cover for access to the decoder, hand rails and round rail around the top of the wood box.

Still a lot of file and hand work also.

I'll be a while.  But it is a start.

So I finally got some serious time up in the RR room today.

Got the water tank and wood box mostly done.  Still need to turn out 8 grab iron stanchions that look alike.  I think as I'll be turning them out of1/16 inch stock rod, I'll cut a tool that will whip them out rather than free cut them and have them all a bit different.  Four will need to be threaded for the cab and four will be a pin for soldering in the wood box side.

The pipe edging shown below was a lot of fun to do. I had been thinking how to do this for a long time.  I've never considered it in HO but in G there is a lot of stuff that can be done.  I took 1/16th brass tubing and cut one side out to get to the tube.  They layed it on there and soldered it down.  The curved parts were curved first so the tubing would not crush out flat while bending.    The electronics will go under the lid of the water tank.

Back up stairs.....

Oh........... what to do on a Friday afternoon.......

I have been working on how to do this one for some time........  The screen scales out to be one quarter inch mesh in G scale and is out of a fuel filter for some sort of army tank.  I have a modeler friend who was in the Guard some years ago.

The hinge was a "can you really do this?" sort of thing.

The ring on the outside was turned out of a piece of bar stock and counter bored to .040" and then a cut was put on the inside for the screen to snap into.

Having too much fun

So I got a few hours today up in the RR room.  Haven't been feeling too well this week so this was the first good afternoon.  Got the front draft gear and coupler made up. 

Also got the hand rails done.  The stanchions are 1/16th stock turned down to a scale inch and a half and the rail scales out at 7/8".  I tried making up a tool to cut them all alike but the brass is too soft and crawls up on the tool. So I had to make them individually...........  not fun..........X 8....

I'm trying to get away for a week to the Oregon coast and then down to Eureka were the prototype is located and operational.  I need to be a bit more up to speed on the winch.  No plans of photos show the valve gear for the gypsy engine that runs the winch very well.

So I got back Saturday night and spent a few days getting back up to speed around the place.

I've been procrastinating about doing the gear case for months.  My maxim for procrastination is as follows:

The sooner you get behind............. the more time you have to catch up.

With that.................    I got these wheels from Allan Pollock at Missouri Locomotive and they came with a gear on the axle that I cannot use.  I am  going to graft in a 1948 Mantua gear case as they work very well and are good solid runners at 24-1.

I need to open up the bronze bushings in the gear case as well as the gear that must be a -.0005 fit.  That's pretty tight for modeling.

This is requiring me to pull a wheel and bearing from one side.  Thus I needed to make a quartering jig for this scale.  I have an HO quartering jig but nothing this large.  So ...... four metal squares later I have it made up.......... in all of it's primitive weirdness.  As seen below.

I have two more of these old gear cases so I have a few tries at this but it is criminal to uses these old parts indiscriminately.

Also I'm putting up a photo of the starting condition of the Mantua gear case.

I'll pull the wheel off next and start assembling parts onto the asle.

I'm back at it after nearly a month.

I got these wheels and bearings from a loco importer and had to take off one wheel and bearing to get their gear off and a gear from an old Mantua gear case pressed on.    Their bearing was WAY tighter than it needed to be.  I'll be relieving some of that before I go back together.

I had to use an automotive tie rod end puller to get enough beans to get it to come off.  Then used a series of straight reamers to reset the gear bore and the bushings that the case rides onto the axle.

This doesn't look like a whole days work but here are the last two photos from this afternoon.

First is the gear case suspension arm.  This has to be flexible as the axles are sprung and all of this needs to float with no resistance delivered to the bushings on the axle.

The U joint cup is seen on the worm shaft.  It is a mid size Northwest Short Line drive line part.

(http://modelersforum.com/gallery/81-200714012429.jpeg)


After twisting off two NWSL dog bone drive shafts due to harmonics at certain speeds I had to crank out a brass one.  It is made from a piece of .125" brass rod, .300" long and ground down.  Then two cross pins are drilled in and soldered. Notice that they are 90 degrees out from each other.  The manufacturer makes them on the same plane; thus the harmonics.  I was in the car business too long and learned that U joints need to be indexed.

Good to see updates Bob.  I am so very impressed by your skill sir.

As far as posting a video, you first make the vid then post it to you tube.  Then you just put in a link to the vid.
At least that's the way I would do it.  That way, you ain't trying to get it to fit here.

So I got some serious time on the Falk today...

I am moving closer to putting in the electric pick up wipers to the back side of the tires and the rear pair will be half hidden in the fire box.  So I decided that I should build that first.

Below are two shots of the fire box.  It is made of .010" brass sheet stock and cut and fitted.  I had a minor collision with the brake rigging so there was some quick peddling backwards but it ended up fitting.

Mornin' all....

Thank you for the encouragement here.............  I'm working on an idea for a removable roof.

Dave......... the decoder is in the water tank, low and behind the cab.  A good friend and modeler here in town found a decoder that is surprisingly compact.  No idea who the manufacturer is.  It came out of something he was working on for yet another modeler.  The speaker is a small square and fits snugly between the rear frame rails.  I put a closed end paper tube around the back of the speaker to concentrate and direct the sound.  I have more of that screen material that I did the stack screen so that will be looking out the back of the loco under the tank. 

Having seen this turkey move now is motivational and I'm ready to get on with some other parts that I have been procrastinating about.

thanx again..............

So after some weeks (months) of procrastination............

Maxim of procrastination:  the sooner you get behind the more time you have to catch back up !

Here are some photos of the roof.  I decided to attempt to make the roof removable down to the ribs.  The front of the roof locates with pins into the front wall of the cab.  The rear are .010" brass that is shaped to the angle of the cab wall tails and hook over the tail.  By squeezing in on the roof sides they move in and release the roof panel.  It actually worked the first time............... You might be impressed but I was amazed !! ! ! !

The pins are soldered to the underside of the roof and when assembled fall over the track for the windows and go essentially unseen.

Next step.........

I made up the brackets for the upper winch shaft.  The upper is the pinion shaft and the lower is the bull shaft.  Please note that I spelled this carefully.

The bull gear runs on the lower shaft and carries the gypsy capstans (spools) and the upper shaft has the pinion gear and flywheel that runs from a small steam cylinder housed in the cab.  I've not even started on that yet.

So here are the latest.

I first made a PVC test jig for mounting the upper brackets.  It is the same size as the PVC core in the boiler.  This allows me to hang threads for mounting that the thin sheet brass wrap would not tolerate.

Ok....

I'm back at it.

Below are photos of the making up and cutting of teeth on the bull gear. 

The first photo shows the raw parts.  The iron ring in the center was cut from a iron pipe coupling and turned down from the outside and counter bored to remove the inner threads.  The disc on the right is the center of the gear and will be cut for spokes later.

The iron ring is a -.005" press fit onto the brass disc.

The stand looking device that the chuck is mounted to is the indexing table.  I have it standing on the cross feed of the lathe.

There is a spring loaded pin that drops into the indexing wheel inside the stand.

I'll put up a photo later tonight that shows it better.

Title: Re: Falk Locomotive build
Post by: bparrish on October 18, 2014, 01:44:35 PM
So here is how an indexing table works.

The Unimat system allows for placing the table in all manner of locations to get most anything done, vertical or horizontal.

It has a series of cores that are cut to different teeth combinations.  I have a 30, a 36 and a 48 tooth indexing core.  They are shown below.  This gives all sorts of options.......... the 30 gives anything consisting of fives or tens, and threes.  The thirty six gives any combination or sixes, nines and twelves.  The forty eight tooth gives combinations or twelves fours and sixes.  Between these three indexes most anything is possible. It is a matter of counting how many teeth between each cut.  With a 48 I could count twelve between each cut and get perfect quarters.

Shown on the actual table, you can see the back side of the index core for the 48 tooth core held in with a snap ring.  The thumb wheel on the left is spring loaded and drops into the various teeth of the core.  Then the core is locked at the top during cutting to prevent any motion.

The trick to making this work is that once you start, neither the cutting wheel or the gear being cut can be removed from the table for any reason.  The chances of it returning to the same location is nearly zero.

You can return to the previous posts to see the gear wheel being cut from the other side.

Title: Re: Falk Locomotive build
Post by: bparrish on October 18, 2014, 02:57:01 PM
So here is the cut gear.  Normally with a gear hobber the leading and trialing edge of the teeth would be cut at the same time.  This allows for the rolling radius of both the bull and pinion gears.

I don't use a hobber so those two additional angles must be cut by repositioning the cutter wheel about fifteen degrees above and below the center axis of the gear.

The rest will be taken out by the pinion gear.  A project for a few weeks from now.

So here is the bull gear off of the cutting chuck and ready to go to a different indexing table lash up.

The brass hub which on the prototype is a really big casting is mapped here for the cutting of the spokes.  The steel gear will be pressed off so that the spokes can be cut out to the edge.

The number of steps for this one part is amazing.  I write instructions to myself so as to remember what order stuff has to be machined in.  This has a LOT of steps.  The gear was times 48 for all of the teeth but the spokes are only times 6.

Dave....

I got cooking and never took any photos while it was lashed up... 

But here is the setup.

I turned out a centering pin the fits in the center of the milling table to hold the wheel center still in case anything moves while I'm moving around the various hold down clamps.

(http://modelersforum.com/gallery/81-231014160055.jpeg)

The following photo shows the spoke wheel being held down.  Each setting allowed me to cut two spokes and then the wheel would need to have the clamps relocated. 

The milling table was mounted to the indexing device and I used the 48 tooth index core and counted eight steps to get the six spokes.  I cut all 6 spokes on one side by turning the wheel then relocated the cross feed to do the other side of the spokes.

It still needs a lot of file and cleaning work but it's close.

So here is the lash up of the pinion gear.  I'm cutting it as if it was a splined shaft.  Then cut it off later.

A hole will be drilled up the center while it is still true in the chuck.

Test run of the gears together.  I designed the bull gear shaft stanchions to be adjustable so as to be able to bring the gears in.  I missed by .010" and had to shim up the stanchions.

The pinion gears is threaded onto the small shaft while the bull gear will be pressed onto the larger.  there are to be two cable capstans on the ends of the bull shaft so that is the next objective.

I started on the gypsy engine yesterday.  This is a small double acting single cylinder steam engine that drives the winch on the front of the locomotive.  The curious thing about it is that it is not reversing.  That means that the loggers that used the loco and winch had to yard stuff in but had to manually pull the cable back out for the next log.  I saw this loco in June in Eureka and the pinion gear is brass and the teeth are completely worn over on one side only.  The other is as if they have never been used.

The cylinder mounts inside the cab and protrudes through the left side front wall under the window.

Pretty amazing.

This then is the cylinder with the packing nut for the cylinder rod and the steel cross head rails.  I had a lot of fun making this up...... only needed to make one.......... that's a plus  ! ! ! !

Really nice work !
It's amazing how many steps and setup's it takes to machine the "old way" compaired to the new macines where you plot the path and push the button to start the machine .
When you machine this way you really have to think ahead and plan the next step and how to hold the part, sometimes it takes longer to set up to cut, than to do the actual cutting.
They say it's the operator of the machine, not the machine that makes a good part.
I think you are proving that to be true.
Very nice !!

Your observations about making a set up are absolutely correct.  I write milling orders to myself just to get things in the right order.  Like holes up the center of things.  Always near the top as often a piece cannot be held well later on.  Also, the hole becomes the bench mark for true center when a part needs to be "re-chucked" for a second or later cut.

Often a setup takes much longer than the mill step or drilling procedure.

I 'm doing all of this on a 1961 vintage Unimat that does not have automatic anything.  Well it does have an electric motor............

Great fun however.

I got the cross head and piston rod done late last night.  I'll put up a photo later today.

So here is the piston rod and cross head slide. 

The prototype has a bronze carrier bearing so I made the whole thing in bronze.  The rod is 1/16th" steel rod threaded to 1-72.  I don't know why the camera made the piston rod look like it has threads but it doesn't.  It is absolutely smooth rod.

The notch is where the connecting rod will go and the wrist pin will be drilled through and be trapped between the cross head rails.  There is no space for screws or clevis pins.

The process of machining is no different with the CNC than with the equipment Bob is using. With the CNC the thinking is being done up front by the designer rather than the person running the machine. We found in the Auto Industry that the best people to do the CNC programing where the good machinists.  The machines don't think they just do what you tell them to do.  Bob you are a great machinist and designer!!!!

So here is the gypsy engine cylinder installed on the side of the fire box inside the cab and the cross head outside.  The connecting rod is three pieces of mild steel and the wrist pin is a trapped clevis in between the cross head rails. There was no space for any screws or like that.

The fly wheel is a made from a throttle plate from an SU carbureter from a 1959 Volvo that I had years ago.  I save anything that is brass.  The soldered closed screw holes won't show once painted.

I still need to make the yoke that holds the cross head rails.  Next part on the list.

The valve gear for this is really easy as this was a non reversing winch.  I can't figure out how they would have used the winch effectively when it only turned one direction.  They must have had to move the entire locomotive into the load to slack off the cables and then pull it out manually.  Had to be pretty exciting with a coupla ton log on the other end of it.

This is serious craftmanship. Nice to see these skills still exist in this draw it and print it age. Not that I'm against 3D printing per se but personally I can't quite get my head around drawing something on a CAD program then producing the result on a machine being classed as modelling.  I guess I'm just a dinosaur.

Here are two photos of the valve gear for the gypsy engine.

I had this urge to make it work.   

The bell crank in the first photo shows the bell crank to the valve on the cylinder.

The second photo is the back side of the fly wheel with the cam mechanism.  The two 0-80 screws are the cover plate that holds the connecting rod for the cam in place. The total throw of the cam is .100"

So the winch is most of the way done.  I have two little support brackets that come down from the upper shaft to the main shaft bearing caps to keep the location of the two gears so that they cannot walk over each other.

The capstans are turned down from 3/4 bar stock with a stepped shoulder inside that locates the capstan on the shaft and allows it to be held in place with a single screw from the outside end.

The fair lead pulleys are for aligning the pull of the cable while logging so that the cable cannot walk off the end of the capstan.

Dave.   

This locomotive still exists in eureka California. I had a chance to crawl all over it last summer. 

The gypsy winch engine only went in one direction.  So paying the cables back out had to be really exciting.  OSHA would be apoplectic. 

I can only guess that at various times they put slack in lines by advancing the loco into the load.  Working with Dolbeer donkey skidders has to be similar.  The problem with both was dealing with the tag line when pulling in a long line.  They would put two or three wraps on the spool and then pull it out.

So after a week off for Thanksgiving I'm back at it.

I turned out a cylinder for the steam turret on the top of the fire box.  Then I brought down piping on each side to run the brake stand and the control for the gypsy winch engine.

The valve wheels are one of the few parts from some manufacturer. They are brake wheels for HO box cars that have a new purpose.  The pipe fittings are wire wound around the piping and flooded with solder and shaped to look like pipe fittings.

The vacant hole on the steam turret is for the pressure gauge.  That's next.

I finished the pressure gauge and flex line from the steam turret.  I  also put the cab back on for the next three photos.

When I turned out the pressure gauge I used a bezel cutter and left a raised area around the frame where I can mount the glass.  Now I have to figure out how to cut a circle from a microscope slide.  Otta take a few tries.

Next will be the finishing stuff on the water tank, filling pipes and drain plugs.

for now...

I have run it.  I put up a short video that is linked on page 8 of this thread about half way down.  I have also run it for about an hour at a garden railroad but I made a short video on my I phone and it turned it sideways for no apparent reason and I don't know how to turn an Apple file.

But it does run.  I have not done any extensive lubrication as it gets everywhere and it will affect how it takes paint.  But there are dissimilar metals at the appropriate places so it runs rather well without oil.  There is a machining rule about dissimilar materials.

We can definitely see the family resemblance between the two locos.  However, the loco above does have an internal main rod (which was pretty common for pre-Civil War locos.)

So I had the locomotive running around the tree for most of the morning and then it ran into some package that had fallen on the track.  The motor in the loco is strong enough to spin the wheels if it stalls against something.  The weak spot is......... or was.......... the cups that the constant velocity dog bone ran in might crack and fail.  I used NWSL cups as they were pre made and pretty quiet. 

Well one failed yesterday so today I made metal ones with set screws.  It spins the tires now ! ! ! !

The only trade off is that it is a bit more noisy now.  I'm going to try and move the motor on its' adjusters and see if I can get a more quiet alignment.

So the holidays are sort of behind us and I got some time on some small detail stuff.

I built the clean outs for the water tank.  They used a cantilever system very much like a wine cask.

Then I added two water fillers on the top of the tank with a hand grab cap.

Post by: bparrish on January 05, 2015, 01:24:17 PM
OK... I'm getting down to the last parts on this thing.  It is exactly a year ago that I started on this.  I must confess that it is a bigger project than I first considered.......... but..... much of it is a self inflicted wound.  As I went along I though of more things that I could make work.  This is one of them.

On any steam locomotive there are a series of blow down valves on the bottoms of the cylinders.  These are what you see when a locomotive starts where there is a lot of steam blowing off at the front of the locomotive.  They are necessary as the cylinders are relatively cold and much of the steam being admitted condenses quickly to water and must be exhausted to prevent a hydraulic lock in the cylinder.  This is also an issue when starting LARGE Diesel locomotive engines.  It is accomplished quite differently however..

I decided to make these blow down valves, also known as Cylinder Cocks or cyl cocks, operate from the cab.

The first photo shows the hand lever on the front wall of the cab.  I have the larger cab removed for construction. Also visible is the control rod that goes out along the boiler to the lever that drops to the cyl cocks.  On the front wall at the top of the manual lever is a barrel nut that I used for an adjuster.  I have a bunch of tubing that threads to 00-90 so they were easy to make up. Don't tell anyone.

The second two photos show the cyl cock rail in its two positions, opened and closed.  It is hard to tell the difference as in scale the travel is only an inch and a half........ about .060" of an inch.

The last photo shows a better shot of how I got this done.

OK....

So here are the last of the construction photos...........  I finished the exhaust pipe for the gypsy engine that leaves the front of the cab and out over the roof.

The last three are the bell bracket and bell.  I got carried away and the clapper thingy in the bell works too.

These are the last of the parts that needed to be made up.

Shane........ at fifty cents an hour, you couldn't afford this thing.  I basically worked on this for all of last year.  The rest of my railroad shows it.  I have some dust and I need to call out the track gang.

I have a graphics artist friend in Portland Oregon who has agreed to make me the decal sets.

I'm ordering the paint on Monday.  I need to find a really low build high stick primer.  I want to use a solvent based paint rather than an acrylic.  My antique Binks Wren gun REALLY does not like acrylics.

So right now I'm going down the punch list of small stuff to clean up in preparation for paint

Thanx again for the encouragement.

Thank you for your remarks.  I've been asked this before.

I went in with the notion of painting this.  I chose early what parts were to be steel as un-painted, oily steel cannot be accomplished with paint on brass.  The bull gear on the winch is an example.

Below is a photo of the draft decal sheets.  Elk River Mill and Lumber Company.
Special thanks to Henry Schmidt of HankInk for making these up.

Here is a shot of the primer going on the various parts of the loco.

I took a lot of stuff apart but I left the frame and such mostly together.  I'm not sure I could get it back together if I tore it all down.  I masked off the tires of the wheels and the cross head steel rails.  Everything else got blasted.

I paint out in the garage and don't have any sort of formal spray booth.  I just go at it and then go back and look for anything missed.

I don't know if I've ever told you about that.  In addition to the 41 Chevrolet pick up, I have a 30 Model A Ford.  In fact I've had it for more than half of it's life.  It was 40 years old when I got it and I've had it for 45 years.

When I taught school I had students who thought that I bought that car new............ they flunked! ! ! !

Regarding over spray.........  Not much chance of that.........  The paint is a acetone base and the carry of live paint can't be more than a foot or two.

I can't believe you just took the whole thing apart. If I did that, I'd have a few pieces left over when I put it back togeather and wouldn't have a clue where they came from.


Great work Bob.....can't wait to see it all finished.

Greg...

That's exactly why I didn't take the frame and valve works all the way apart.  I didn't make up an instruction book as I went along.

It had to come apart some as there are too many places where there would be no way to get the paint in there.

Thanx for your remarks and for looking in.

Hey Bob,
Awesome stuff!  I can't wait to see you running this little gem on the railroad!

Any chance that you will be at next weeks mini meet?  We will be running Jimmy's old "Run away Ore train" for the first time since Jimmy's death over at Bill Chapman's place.  Turns out I had the train (i.e. the 80 mini Ore Cars) and Joel got the Bigboy.  So it's kind of a joint venture between myself, Joel and Bill.   Hope to see you there!

Hi Bob.....growing up near Oak Park, did you ever get over to Petersen's for their ice cream?


I had the worlds best pistachio there when we were on a visit to Chicago back in 1987.
Title: Re: Falk Locomotive build
Post by: bparrish on February 27, 2015, 03:11:04 PM
Greg................

I don't recall the name Peterson's.........

Recall that I left there in 1966 for my all expense paid trip to Viet Nam.

I did get to the center of Oak Park and the business / merchant district with some regularity. 

My favorite place was the Esquire Restaurant at Madison and Oak Park Avenue.  It was run by a shirt tail relative in the Greek community who ran the restaurant into his 90's.  That was in the early 1960's.  Uncle Louie knew everyone in town I think.  He and my grandfather were cousins and no one had a chance when they got into swapping lies.

I named a building on my railroad after him even though his place was a corner store front.......... I built it as a diner as part of a conversation with Candy some years ago.

So here are a couple of shots with the grimy black on the various parts.

Some of it went a bit dry so I had to wet sand a few parts.

Now I have to wait for about three or four days for it all to gas out and firm up.

For you boys in the east.......... it's gonna be in the 60's by the week end so I can open up the garage and speed thing up a bit.

Then seal it all with clear flat and then start back together.  Otta take about a week to get it back together.

Thanks for your  remarks.....

I have it painted but reassembly is a bit slow as I'm finding that I made some stuff so close that paint takes up space.

Never had to deal with that in HO.

I found an old jar of Oily Black acrylic that has just a hint of metalic in it so it reflects a bit of light and looks really wet and greasy.

The Falk is going back together with paint on it.

Put the electronics back in today and decided to see how bad I hurt in by taking it apart, painting it and stuffing it back together.  I am amazed how many fitting steps had to happen all over again.  I guess paint takes up space.

So here it is.

Martin...

When I was at Mercedes Benz we had a device that could be placed on the surface of a hood or trunk lid and it would tell the thickness of the paint in hundredths of a millimeter.  There really wasn't much there but they, like other manufacturers made a science of making paint stick to stuff.

They even had a paint at the time that was more flexible which they used on the sides of the cars from the door windows down to resist door dings.  Then they had some stuff that looked like it had styro bead in it that they used along the rocker panels. Pretty amazing stuff.

The difference in what they use and we do is the amount of " build " that they put in the paint. The manufacturers and the body repair businesses both have a primer that will hide a 30 grit sanding scratch.  You could hide and entire HO locomotive  under that  ! !  ! ! !..

Our paints have very fine ground pigments and thin carriers to get it on there.  Then the distillates are designed to go away to nothing leaving all of the detail showing.  Car makers don't want that detail showing.  People expect very smooth shinny finishes.  We want flat weathered finishes.  Cars get to look like that after a few salt winters in Boston but not when new.

Thanx for looking in.

Bob,

I now understand wny I could not afford a Benz. Kidding aside...that was really interesting about the paint.

I noticed that the acrylic paints leave a thicker layer than the old Floquil paints. I like staining and chalks for wood, but on medals, give me Floquil any day.

In the absence of Floquil I have gone to Tru-Color out of Arizona.  When you order you must tell them for spray or brush/  I suppose you could order everything as brush and thin it as you like.  They recommend acetone for a reducer.

Hmmm,   I didn't know you could order Tru-Color for brushing.  I'll have to try that.  It sprays very well (except for the solvent, not a good idea to do much of that in my enclosed train room next to the gas furnace and water heater...)

That must be the absolute minimum locomotive cab (controls and gauges)...  I'm sure the prototype didn't spend money on anything not absolutely necessary.

Title: Re: Falk Locomotive build
Post by: bparrish on April 09, 2015, 01:50:55 PM
Dave.........

The controls were monumentally simple as most locomotives at that time did not even have brakes and they used the manual brakes on the freight cars to stop and secure the train.  The levers are a brake system that was driven by steam pressure with an oiler, throttle, direction control and the lever down low on the right near the floor was for the cylinder blow down cyl-cocks.

So here is a photo of the pressure gauge that I finished this morning. I cut a piece of microscope slide glass down to .300" and put it in the recessed bezel that I turned into the gauge when I turned in on the lathe.

So I'm getting close now. 

Need to make up a wood load and a broom.

I'm still massaging the chalks but I'm pretty happy with the subtle rust tone on the boiler and such and the cab, which is wood, a matching non rust color.

Also in are the movable windows.  They are cut from microscope slides and glued into the brass frames.

So what is next ? ? ? ?

I'm speculating on building a self powered gas motor passenger car.  Put into your search ... Lancaster, Oxford and Southern.  It is a chain driven motor that is at Strasbourg PA.  I saw this first in 1992 and it has since been restored to regular operation.  I have a niece who lives near by and did some measurements for me some time ago.

The idea of making the chain drive operate is a very cool notion to me.  I'm also pondering G (or what ever half inch is really called) scale again.  Half inch is really easy to scale up drawings to.  How did we ever get HO and the weird fractional metric number ? ? ? ?

I'm still some time away from starting.

Gents.........

Although I am taking the Falk to the NMRA national, I had a a few local friends who thought I ought to have it judged here first and see how it does.  I think they mostly wanted first crack at it before the national.

So the judges were a fellow local modeler who was the Achievement Program chair for many years for the Pacific Northwest Region. Second is the current AP guru for the 3rd division of the PNR and the third judge was the  current president of the 3rd division of the PNR.

It was fun to sit in on the judging using a new judging rubric that allows the modeler to be present.  This rubric was created by Jack Hamilton of the PNR and he is the national AP adviser (or something like that).

I supplied all of the usual documentation for their review.

They scored me at 128 points.

I thought it stopped at 125 but there are additional points for certain scratch built components.  The original score was 124 and they they added four four the scratch built stuff.

It was flattering and humbling at the same time for the complimentary stuff they said about the locomotive.

I know that I enjoy judging and being around some great modelers.  It was interesting to be on the other side of the table with this.

I want to thank all of you who followed the thread and offered encouragement over the year that I built this.

It only made me want to do things better.  I have a small box of parts that were set aside as they were not good enough with the first try.

Thanx again.

Great news - Good luck at the Nationals.  For those judges that are watching the thread Bob should get extra points for his skills demonstrated as a machinist.

Tom...

The judging was not associated with a competition or a semi annual meet or like that.

There was a cadre of people who wanted to judge it before I took it to national.

With that there was no placing.

see ya

So here is the verdict at the national. 

I finished second, out by one point.

I took first in the popular vote on steam locomotives.

Thanx for all of your support through all of this.

See ya
Bob

Bob, great outcome, though I (and many others here) think you and the Falk deserved first place.  You will always be first place here!
