People always ask if I can make and send them a sissy bar long distance. I don't have any jigs that I form my bars around, I free-hand bend each bar I make to fit the client's exact fender, frame, and wheel component combination. I figure out how high the bar needs to be, cut my material to length, make a soapstone center mark, fire up the torch, and go from there. That's something I can't do from 1,000 mi. away.
No two sissy bars are ever bent the same, or mount the same - they're all just a little bit different from each other, and that's what makes them unique.
