Works with motorbike tanks.
Thanks for your idea joolstacho. I had thought about your idea before as it happens (honest). But I wondered about filling the holes after doing the actual dent removal. There are about six or seven dents in all, close together right around the curve of the tuning slide and a bigger one eight inches from the bell. I can see it would work providing I use wet cloths as a heat sink each side of the brazing to prevent melting the soft solder which the trombone's joints are made of. But there isn't enough space to put these cloths between the holes on the tuning slide. Do you think the heat from a hole that is being brazed would melt the brazed hole(s) next to it?
