I had Sully weld up some SS connections for me this week onto my kettles and some SS tubing. Crazy fast turnaround and great looking welds. He is in mid-county. Call him if you need some welding done: 314-601-4100.
Sully welded a few 1-1/2" Tri clover fittings to my kettles (for electric elements) and some additional tri-clover fittings to a counterflow chiller. His prices were very fair but I recommend you talk to him direct about your specific project for an actual quote.
