Of course this will be true brazing! It cold be hit and miss a brass is a moveable feast. I suggest you try it, using borax as a flux, on some scrap and see what the reult is like. Neil

I get twisted scrap from my metal supplier, it seems to work quite well on small stuff, can't get enough heat with my LPG set up for large jobs. Hav'nt had any success with brass filings, maybe I'm doing it wrong. Ian S C Edited By Ian S C on 15/01/2011 01:57:45
