Stainless Steel "Bell" Barrels

I have some thick-wall 316L SS hemispherical tanks that I'd like to sell, and thought they'd make perfect barrels for rocket mass heaters.  I think you could cut them in half and build TWO stoves, but it's not my area of expertise.

What do y'all think, good candidate?  These seem like they're 3x as my open-end hog scalding drum.

Hi grant;  
Those are some pretty high end pressure tanks.  Seem's a shame to cut them up.
What diameter is it ? It looks to be less than a 55 gallon barrel?
They are nice looking, but a thick skin is not the best in that location.

Wow that is a thing of beauty!
If I lived a couple of thousand miles closer I would be very interested.
