I had a question for you guys that have had their couplings welded to their kettles. Did you weld the couplings THROUGH the kettle - e.g. drill a hole large enough to put the whole coupling though it - or simply drill a hole of the same size and rest the coupling on the outside.
I was thinking that a coupling that went through the kettle would be better but I want your opinions. I won't be doing the welding myself - I found some very experienced welders to do it.
