I was gifted an older US Divers Steel tank. And I'd like to turn it into a bell. While it hasn't actually been condemned yet, 1) someone has taken liberties with a pipe wrench and the tank neck, 2) it appears to be a pipe thread tap.
My base question is how much do I need to take off the bottom to get away from any widening of the wall thickness, but not lose too much length? It obviously isn't hyper critical. But if someone knows, then I get it right the first time. I am going to be borrowing a buddy's time and equipment and don't want to ask him to make multiple cuts (If I were to simply err on the long side).
2250 PSI, US Divers, born on date '59. 6 3/4" diameter. Roughly 25 1/4" bottom to top of neck.
