Set it up to catch rainwater?

If you can find someone to cut it; cut it into two round tubs and one round ring from the center. Use the ring for a firepit.

Cut in half the long way, they make huge BBQs

Hi Rain1950

Thanks for the reply and suggestions. :-)

However I should have said 20 lbs tank Not 20 gal. (seniors moment here)

I was playing with the idea of how I might make (get it made) into to a hotwater tank for my woodstove to heat or a passive solar water tank even though it is small. (have plans for old hot water tank).

Although both these tank are so different....*sigh* wishing I had more knowledge.
Anyone with an idea if that might work?
