My local welding supply has them which is convenient but more expensive. I think that I also used to get them from Grainger.

Depending upon what you are looking for, thread-o-lets, and sock-o-lets can be welded into tanks for pipe connections. Plumbing supply houses usually stock these things and may be a local solution.

I just make them on the lathe.

Same, Except I brass brazed and silver brazed mine in, Because I did'nt trust my mig welder not to blow huge holes in the 20 gauge tank I was working on.

(Brass braze reenforced an existing one that leaked and had no 'fillet' around the base and created a huge smooth fillet, and silver brazed one I made that had a huge fillet inhairent to the design and only needed the good wicking action of silver braze to be insanely strong, secure and sealed)

I've only welded in a zillion or so of the damn things. Is there any way of welding them so you don't have to touch up the port with a pipe tap? I tried all my tricks but the pipe threade still go egg-shaped. I hate it when it takes seven wraps of teflon tape ito seal.

Use as little heat as possible to get er dun.......most of the problems start with differing thickness of bung to vessel and bung itself. Be a pain in the butt but the best way would be to weld in a blank bung and then drill and tap after it's cooled.......then you still have the correct shaped fitting.
