I am making some brass bolts for saw handles. I will be getting some brass rod for the shaft, and flat stock for cutting out the large bolt heads. My plan is to braze the brass rod onto the heads, but I have never done brazing before. I've done plenty of electronics soldering, and a bit of welding, but never brazing.
I have borrowed a propane torch, and some silver brazing flux, and I have some 5% silver brazing rods.
It's probably a couple of days before I can get the brass, but I just thought I'd ask for hints in the meantime. My plan is to clean the joints with wet-dry sandpaper, then set everything up on the concrete, cover the joints in flux, somehow hold the bits in place, and turn on the heat. I'll keep trying the rod onto the joint and hopefully eventually it will just start melting and running in.
Also, the flux is quite liquid, probably the consistency of washing detergent. Is this OK? I shook a new pot in the shop, and it didn't slosh around. Mine could be quite old - does it go off?
