Nice unpolished and unmolested No.30 with decent patina and now a reassembled original cast pan ring. Finally brought back to life with new set of seals almost all round (have yet to find a good match for the seal inside base of the stubby pressure release). Other than the still leaky pressure release seal, the main remaining dilemma is whether to do anything more with the pan ring. There is still a gap where one fragment has been lost. But filling the gap with new weld, then grinding to shape, would run the risk of causing more problems than might be solved. Argon arc MIG with stainless filler wire is the most viable type of weld on this fragile type of casting, but filling, as opposed to 'simply' joining breaks, runs even higher risks of major meltdown and/or new stress fractures elsewhere in the ring if cooling is too rapid. The balance point between joint failure due to lack of penetration and complete blow-out is very narrow on this material!
