Thanks Ken, you confirmed my thoughts about the speed control and reverse action. If the center of the flywheel were dished a little you could achieve a true neutral with no additional wear on the friction wheel. Very cool, thanks again for taking us through this project.
Hi Ken, going back to your third reference pic I see now how the transmission of power gets transferred to the drive axle. It is the friction drive between the engine flywheel and the small spoked friction wheel. No gearbox required. Dash It All!
great work on the drive line and chains! Scale roller link chain can also be had at MFH and Micro-Mark railroad accessories. Not everyone wants to invest their time and big bucks in machining equipment just to join the "Real" world.
Fantastic eye for detail Ken, and skilled draftsmanship. Love the break mechanism, springs are bear in CAD.
Thanks for sharing your project with us, looking forward to getting color on this cutie.
Hi François, Looking at the 1:1 green leather in the previous post I would suggest trying a reverse casting of a fine grit sand paper as a possibility. 380 or 400 grit coat liberally with mold release and spread a thin coating of urethane mold making RTV this should give you a dimpled surface more closely resembling the leather and be fairly flexible.
Not to get too far off topic but Fernando does post the 251 fairly often on theebay auction site. Bellow is one that Curt Raitz had at NNL West22. I navee several of the FP models and am fascinated by Fernando's use of embedding wires for the suspension or in this case for the fender mounts!
Looking forward to the rest of this build.
