Lower Frame Rails

A crucial aspect to the build was getting the two lower frame rails tacked together at the correct angle. The lower frame is what everything else on the bike is going to be squared to and if this is messed up, the bike may not ride well, parts may not align and the look of the bike will most likely be compromised. I squared it by clamping the top of the two upper tubes and making an 11" spacer out of MDF. (Sorry no pics) Then when all the measurements lined up, I mocked it up on a board with a center line drawn down the center, making it a centering jig. When the rear was aligned with the front, I knew I would be able to tack on my braces. I aligned the rear by setting my MDF spacer right on the line of my centering jig and ran a plumb-bob down from the center of my upper frame rails until the angle was correct so that everything was aligned. I then tacked the frame to the braces and I was done. With what I had to work with and my experience, which was none, I think I did pretty well. I have a few pics that I took after I did this with the motor and a few other pieces very temporarily mocked up for your viewing pleasure.
