20 inch dia, 1/4" wall , ill put it aside for a future build, but im more interested in the end cap on the left. What a perfect circle guide for the plasma for 18" and 20" circles!
I'm gonna agree with Ribwizzard and say that it is a "~~ Klingon warp generator " and that it will make an out of this world smoker of some kind!Don't know what it is, but it looks like something we have pulled from old orange grove well pumps.....
I am sure you will figure something cool out for it.
