What do you have as far as shop equip? Such as welder, drill press ect. You are going to need more than just hand tools. If you don't have a shop you may want to buy the one from Barry off of e-bay. It should end up looking something like this. Engine needs to be offset 7/8" off the centerline of the frame to clear the 4 1/4" back tire. This one was fabricated from 6061 Aluminum.
