Short update, my custom bobber project is moving, albeit slowly.
I have got a contractor in, you guessed it, India, modeling my chassis.
I am using plans available freely from chopperhandbook.com but that really won’t help me get the bike registered. The engineering signatory will want evidence the bike chassis is sufficiently strong so FEA is one way to demonstrate that before you start cutting steel.
Even though I am an engineer, I haven’t done a lot of 3D modeling or any FEA, so I had to find an expert in this area. Elance has tons of people around the world who can do this work quicker and better than I ever will, so I’m paying someone to do it.
Chassis model is finished and pic is attached. Next step is springer front end, then stress analysis on the whole assembly.
