Aren't the rear two axles on the prototype tender a pivoting truck?  How are you going to get that tender through a curve if it's a rigidly mounted three-axle tender?  Or is the plan to 3D print the tender frame and cut the truck sideframes off for the rear two axles?

If the wheelbase is short enough, it ought to work OK.

About the rigid tender. The Atlas 2-6-0 has 4 axles on 2 trucks and none of them pivot. I remember an old Tyco HO scale steam loco that was powered by the tender, it has stiff trucks as well.

About the cab front, what?  The cab front is flat. The EBT loco had a different taller cab without the curvy roof, but the D&RG drawings show the same roof as the proto photos.

Well, I guess my point is what makes you think it is rigidly mounted?  Do you have detailed plans that confirm that is rigidly mounted?  The picture you posted clearly has daylight peeking through over the sideframe.

Oh no in real life it has a pivot  :)

In fake life though it will be easier to keep it stiff.

This is the Atlas 2-6-0:

The tender trucks are mounted solid to the side of the tender, no bolsters at all.

Yeah, I was talking about the #1, not the #6.  The #6 clearly looks flat though I thought the #1 looked like it might be angled.

Carry on.

i remember a Bachmann 2-8-0 in HO that was tender driven. the powered wheels were fixed -- 1 axle per truck -- and IIRC the truck sides were somewhat enlarged so they could pivot with the other axle per truck. i think it was the middle two axles that were fixed and powered. anyway, other than the atlas/stewart diesels it was the best running and best pulling locomotives in that day (later '70s and early 80's). thanks Chris for stirring those memories. they were some good times!

Here is that old Tyco 2-8-0:

I know it's highly unusual for me, but I started another project  :P

Probably 20 years ago I tried to make a HOn30 Climax out of a LifeLike SW. I posted it a while back:


At the time I just glued on some HOn3 sideframes and it looked pretty good, but it is too short. The LL SW wheels are a little bit too large in dia, but that is perfect for HOn30.

Figured I would give it a try again since the world has 3D now. I dug out a bunch of LL SW parts and made a new frame out of a fiberglass circuit board just because it was stronger than only styrene. I did put a layer of styrene on it to get the thickness right for the trucks to clip into. After I stretched it out I took some brass rod in the lathe and made a connector/flywheel to add another piece of shaft and stick the worm out further.

This is what I came up with:

I would be a little leery of having a flywheel & shaft assembly sticking out that far without some bearing support to stabilize the shaft.

Probably could run the shafts longer beyond the worms to add some support?

Chris,

Looks like a great start, I'm looking forward to watching your progress.

There's a prototype for everything.
If you can't make it perfect, make it adjustable.
DCC is not plug-n-play.

I took brass Climax sideframes and put them in my scanner. Then traced over them to a 3D print. Glued the new sideframe on to the LL trucks.


And it runs! Just as slow as a stock SW. The long side of the motor is only 5/16" longer so I'm sure it will be OK.
