Hello everyone! I need advice from people who have used bronze before. I am using bronze for the first time for my sword fitting. Pommel and guard mostly. I have never used bronze beforehand my questions are what type should I use. Should I lean more towards a silicon alloy or tin? Also where is the best place to find bronze stock? I have looked online and it had been more difficult then I at first anticipated. Any advice will be much appreciated! -Jukebox
