That's pretty cool! I'd like to see how a McKeen power truck would be made. Although I wouldn't be making such a thing, it would be neat to see how a large driver and smaller driver would be powered with an axle hung motor. Hmmmm...


Woodie-watch what you ask for!

One time I ran into a similar situation--a "Maxium Traction"  power  truck for a trolley. I put one of the motor/Gearbox units that I was making at the time on the large wheel and wanted to power the other (smaller) wheel also. I used Delrin sprockets and chain. The ratio wasn't perfect but it was close. Worked great--the car climbed grades on my old layout and the wheels NEVER got dirty. the mismatch slip kept them clean.

I can dig the car out and take some pix, if anyone is interested.

Want to see also!.
BTW probably is easier to make/find proportional pulleys. This way a closer to exact ratio is possible.

OK, will excavate.

Jose- I would never again worry about getting ratios close. Pulleys--I don't use rubber belts, as they usually require dis-assembly to replace. and create too much friction. Sometimes I use fine wire "spring belt" as that can have the two ends connected in situ--but I probably was out at the time, and hadn't set a lathe up to wind another 10 or so feet. Been a while, so I can't remember the exact circumstances.

I hope that Deere John (the backhoe) starts.......
