Default Re: Making a custom bike engine

That would be awesome!
Right now I'm starting to price out material. I'm going to make the crank pins out of 303 stainless, which has a feild strength of 40,000 psi and a tensile strength of 95,000 psi. A 3/4" rod that is 12" long is coming out at about $15 before shipping.
I might start ordering material for the crank pins in the next couple of days
Production should not be to far off!
