Without a doubt the most expensive, slow, frustrating way to build a bike. Your best bet is to buy a compete bike, even if it isn't running and modify, fix and repair as necessary. You'll be money ahead, and it will be finished sooner. I just purchased a 75 FX in good shape with a new Jims 5 speed off Craigslist for cheaper than than you can imagine. The deals are out there. Cash is King. If you don't have the money, save up and you'll find a deal when the time is right.Has anyone done this? I'm just playing around with it in my head. Starting to think maybe I can piece one together... Any sage advice, wisdom or insight would be helpful.
