      Fun if everything turns out right and PITA if they do not.
      Check, check and recheck as you drill.
      Use good drills, Not so good drills give not so good results.
      You get one good shot at getting it right.
      Leave nothing to chance
      If it is not going as hoped, STOP and study
      the situation. If things are going bad, going ahead
      usually makes things worrse not better.

        Louis, good advice for pretty much everything in life!

            I just pulled the tank apart a little while ago, after I let it sit
            in the wood stove “hot air” pipe for about an hour.
            It came apart relatively easy, though I have not tried turning
            the studs yet, nor have I looked for some thick glass to
            use for lapping the tank halves.

              Treat the studs as if you know they will snap if forced, Putting a pipe wrench on them will work IF they are in the mood to be cooperative.
              AND a very BAD idea if they are stubborn. It seems to me you have
              gotten past the hard part, with some careful use of torch and gentle
              persuasion, I think studs will be cooperative,
              The studs are 2 long and 2 short, I have, in past ,attempted to reseal with studs in wrong sport…oops!
              I use the mirror door from an old medicine cabinet… metal back and
              band around edge ,seem much safer than a piece of plate glass.
              Found in trash many years back, kept it ,as something too good to
              throw out , only took 25 or 30 years to fine a use for it…spent about 3
              weeks looking for it when I realized its time to be of use had arrived.

                  Some day I’ll make a handle for that brass hammer. Just happen
                  to find a bolt that fit it! Will try “smacking” the bolts tomorrow…..
                  after I get the snow taken care of…….. almost a blizzard going
                  on right now.

                    All the studs in the tank came out with ease. Whacked each one with the brass hammer,
                    got the torch out, and within three minutes had all four loose, then soon removed.
                    Wish it was always that easy!

                      Glad you were able to get them out so easily. You’re right – if only they were all that way…..
