What to do with that old well tank?

Picture of What to do with that old well tank?
So, I had to recently replace my 44 gallon well tank at my house due to the rubber pressure seal on the inside of the tank leaking.   After hauling the heavy thing  out on the lawn, I decided to cut it in 1/2 and make it into a fire pit for my patio and camping!

CAUTION:  Well tanks are under pressure even after being disconnected to the water supply.   Make sure you deplete the pressurized air in the tank at the needle valve (usually on the top of the tank) before drilling into the tank.

I drilled a 1/4 hole right below the middle seam in the tank (where it was welded together)   Once I had the hole, I took a jig saw and followed the seam all the way around the tank cutting it in half (pretty easy using a metal cutting blade).

Once it was cut in 1/2 I removed most of the rubber diaphragm using a box knife.    Add wood, a little lighter fluid and enjoy!   I plan on repainting the outside of the tank with high temperature paint once the old blue paint is burned off.   (and until the rest of the diaphragm is burned off I wouldn't recommend roasting marshmallows yet).

I turned mine into a BBQ. took a little work getting the rubber diaphragm out but it works great.

I made ours from a washing machine drum with a big rig brake drum welded as the base.

great idea ...of course my opinion is bias because i made the same thing last january LOL. it was cut and 3 36 inch steal strap was purchaced last august with the intent of drilling and bolting the legs on. i got a lil mig for xmas n decided this was my test welding project. i clamped a leg on marked where i felt it needed to be bent and "eyeballed" the bends in my vice. once i was happy with the shape of the leg, i used it as a template for the other two legs. welded them on, cut some heave expanded metal mesh for a grate to keep the fire off the bottom for heat circulation, painted it the high heat bbq black paint, and have cooked three meals on it already.

It doesn't get much more enjoyable than sitting around a fire with family and friends. I have a large LP Gas tank around 9'long and 3' across that someone cut a "door" out of to make a BBQ grill or something, it was here when I moved in 22 yrs ago and has been a fire pit ever since.
