I don't know if this is how you want to do it, but maybe an old hub and a plasma cutter would be easier?? That's a fairly big chuck to grab that diameter on a lathe.
Carl, diameter is 15.5", they are 23.5" tall.
Steve, I'm a homebrewer. Looking for another kettle and since I have a keg it's the least expensive way. They're called Keggles:

It is big, but I need the opening to be a perfect circle for the lid... Not sure if we could get that cut from a plasma cutter?
Dang, my lathe is a 15" swing...so no dice.
A plasma cutter with a circle-cutting jig would be fast and easy, and probably a good enough circle? (I don't know how "perfect" is acceptable though...?)

Carl,
Sorry, not explaining myself very well. I need to cut a 12" hole in the top of the keg. The diameter at the largest point (in the center of the keg top to bottom) is 15.5". Does that change anything? I just don't know anyone any more with a plasma cutter and circle jig, and my skills with cutting torch will not lend anywhere close to a circle.
Tacoma; thanks for the tip. If Carl can't do it I'll likely call them.

Nope, doesn't change anything. The largest diameter anything I can put on my lathe is 15".
If you want to bring it over, I'm sure we can figure out a circle cutting jig easily enough.
my uncle has a machine shop, and he can chuck on stuff A LOT bigger than that. Give him a call. Ron 801-633-9721. Piping Machine Specialties.
