Not the reasons why brazing on would be better. That's pretty obvious.
My question is, would JB Weld or some similar epoxy be strong enough to hold shift bosses to the downtube?
It would help me out a bunch if this solution works:
1. Don't have to buy a brazing rig
2. Only lose the paint where it's necessary to glue, not the whole brazing area
3. Low stakes in terms of safety
4. Bosses are $20, let me use a 7400 group with 6-speed shifters
Thanks for your experiences with epoxy
