Well for what it is worth here is my current distraction (last 3 months).
Scale is 1:16 (of coarse)
It is 16 3/4" long and 2 1/4" from the rail to the top of the frame.
36" gauge. I hope to have it electric and R/C (another steep hurdle!)
I did not make the wheels or the gears, everything else is from my hands & machines.
I did not use CNC; I count, subtract and add hand-wheel numbers and rotations.
I draw with a pencil on paper.

Frame, still under construction;


Front truck


I am still working things out.
The screws are long as i am not done with the assembly & disassemble and reassembly......
The truck has three dozen 0-80 fasteners and weighs a pound and a half..

The name "Wizard" is because of a good friend who offered assistance and Lima blueprints when I spoke of "trying" this project out. Without "The Wizard of Willits" help, i would not have been able to even get started.

More to follow.
Thanks for looking,
marty

Marty, this is great and I look forward to seeing more progress! I too enjoy machining on a small scale and happen to be working on an "Elmers engine" now.

That thing is really coming along well. Do the gears mesh smoothly? They look perfect. -- Russ

This is gonna be one of those ones you don't really wanna paint, and then hide a lot of the craftsmanship behind it.  Great start Marty, and I'm sure this will be a pleasurable one to watch come together.  All the best with the rest of the project.

Cheers,
Dan

Simply lovely craftsmanship, and one hell of an undertaking. Kudos. Unfortunately it like the other brass work on this forum is so far out of my realm of skill and ability, I dont know what else to say. But I am very happy to finally get a glimpse of your progress on this, and look forward to more.

Thanks guys!
It has been a real challenge and a wonderful learning experience.
To answer Craig's question it is based on a 13 ton Class A with 6x10 cylinders.
Any questions, please feel free to ask!

Your work is just beautiful.  If I had half your talent I'd be happy.

But the real question is are you going to make these in On30 Wink

Iv'e been watching this one. Your fab and machining skills are quite wonderful. Way beyond me too, but fun to watch.

Hi Marty,

that looks great.

I would however like to see the other side without the bevel gear.

Why yes, of course! Would i settle for anything less?  Grin
I spent a lot of time fine tuning the backlash down to .002" - .003"



Here is the "plain" side of the truck.



I did not use the normal spoked wheels on the "drive"side as they are hard to see, also this made securing the bevel gear easier (for me) any way. The wheels did require some modifications for my use though.

And here is what I did to spring the axle bearings on this side.



The bushings are aluminum so I can replace them if I wear them out and not the axles (steel).
Also there are lube holes (not shown in this pic) down through the bushings to lube the axle.

It's no wonder they always show the guy with the oil can walking around the locomotive, there are numerous places for oil/lubrication. I have tried to plan for a way to do this as well.
