To me, the purist form of custom bike building is chopping. It all started there. Guys got stock bikes and an hack saw and went to town. Most people, including my self in the early days, didn't have the tools or means to make scratch frames or tanks, so we used our creativity, and elbow grease to make the stock bike our own. Don't get me wrong, I love making things from scratch, but sometimes just slightly tweaking something to make it your own can be just as rewarding and well, just as much work, if not more work.
