[TheForge] NEW - weld question

Sat Apr 26 01:44:00 2003

Greetings,  

Although you probably could get away with successive passes with MIG, I 
have to agree with George.  If you can weld, have the equipment, etc, 
stick welding with low hydrogen rod is good advise.  If I remember 
correctly, you and I live close to one another.  If you need help with 
the welding, let me know.  BTW, I'm not putting my two cents in here to 
drum up work. Yeah right.

Cheers,
Bill Woolley
