I've been in a real slump lately, nothing really had me fired up.
Been talking things over with my buddy (Jerry Trains 1941) but not much I really felt like doing.
He has been bugging me to work on a machine shop.
I pulled out my Western scale 1:48 planer and then thought of doing one from scratch in a larger scale. I thought about 1:22.5 but finally decided on 1:16.
go big or go home! right?
I really enjoyed the scale when doing the Plymouth.
So by using the 1:48 parts and plans here is where i am after a good weekend.



overall length is 15" and height is 5 1/2" right now. The large pulley is 2"
Base is MDF, sides are styrene

I am able to build most parts and have almost enough pulleys.
BUT, I am at a loos how to make/find the "rack gear";
a long flat gear about .090 - .120" square. Any suggestions?
I know I could build one form triangle strips.....but that's a lot of work!

I found this in an old printer .. it's about .160 wide but since is a rubber belt could be narrowed. If you have any old printers .. you might get lucky

My rule of thumb about scale: Small scales for layouts, large scales for models and dioramas.

If you build a layout you need as much mileage as possible per foot. You need as much impact as possible to wow people (or yourself) with a model.

This should be a nice model! Good suggestion Ed.

Thanks Ed, but i bet it would be a bitch to attach and paint.
The more I think about it I will likely end up milling my own.
I only need two, 4 1/2" long, shouldn't take more than an hour on the mill.
Would be a good candidate for rapid prototyping! Oh well.

How about making an oversize (in length) trough that you could fill halfway with clay or the like, and then use a round gear to impress "teeth" into the flat surface?  You could then pour resin into the "form" and make your long flat toothed part.  The only real trick would be to find a round gear that was wide enough for your needs, although I have used multiple ones ganged together to beat that particular problem.

Dave at Vector Cut might be able to stack laser cut strips from your artwork.

Try some of the electronic companies like Maplins or http://www.motionco.co.uk/gears-racks-c-32_42.html they all do a wide range of racks and pinions and some are very fine.On my workshop drill stand I did it the long way flat strip and separate teeth - then of course I found these suppliers - that's life !
That's some inspiring work you are doing just keep it coming

I'm gonna try and make my own, I think I can...................
Started playing with the setup today, we will see.
If not then i have a source!

Gil, I dont think the r/c stuff would work, plan "C"

Actually R/C cars use servos, no racks.   Stock Drive Products carries that kind of thing;

Well your off to a good start.  I think there wouldn't be a problem for you to make that part.  Or for that matter any part you need.
Hell you were crazy enogh to start this monster!!!! :D

Got the rack gears made last night!
Only took about 30 minutes.
I used .060" x .100" styrene.
Turned out great! Pics soon.
