Is there a tool for removing dents from bike tubes?
I have considered buying a couple of really top bike frames over the past several years with dents in them, convinced that I could build a tool that could be slipped inside the frame and force the dent out, leaving me with a great frame for not a lot of money. I have drawn up my CAD plans for the tool and have access to a machine shop but have not yet done the machining. My question is, does such a tool (or technique) already exist and would there be a market for such a tool among frame builders?
BTW, I understand that there are limits to what reasonably and safely can be repaired.
How often do you see someone bring in a dented frame for repair?
