I used a hole saw to drill the holes for the Stainless Steel couplings. It was surprising how easy it was to drill through the keg wall. Standard high speed twist drill bits do a very good job for small holes.
All welding was performed with a MIG welder and SS wire. This was my first time welding Stainless Steel. The welds were cleaned up a bit with a sandblaster. It is important to let the tun sit empty for a couple of days before use. This gives it time to build oxides on the surface. If you fill it with water too soon the welded areas will rust!
