Metalwork: How to solder a joint close to an existing joint without melting the first one? Answered
I'm trying to make a sculpture by soldering copper/brass rods together, but when I try to make one joint, it melts all the surrounding joints. I tried putting on some heatsink tweezers but they weren't effective. It's going to be quite complex, so clamping the whole thing and soldering all the joints at once won't be practical. Any tips for making a better heatsink? Should I just solder faster? At the moment I'm letting the metal get really really hot because I guessed it would make a better joint, but maybe I'm overdoing it?
