So here is the deal I am building my first break drum forge and I have basically everything I need. I just need to know what type of washers, bolts and nuts are safe to use to bolt the drum to the flange on the pipe. Now I understand galvanized is a big no-no, but according to anvilfire's safety section on fumes you shouldn't be messing with stainless steel either. On another thread in this form I read to use stainless steel. the link to that particular thread I mentioned is below. Sorry if this is a re-post I searched the forum and did not find a suitable answer.
I have picked up "black steel pipe" not black iron pipe to use and just wanted to know if that was safe as well.
