Been looking for something like this; they don't seem to exist. Haven't really been able to find any "parts" other than firebricks at Tractor Supply. Concrete blocks will work... for awhile... but disintegrate. Guess they can be replaced. Is chicken wire or some other kind of wire fire-proof? Anyone ever built something like this? Just need to burn limbs and brush trimmings on a regular basis.
Ugh. Hard clay soil. May not have too many other options. Nobody seems to sell ventilated oil barrels anymore-- although I'd like more volume than that. I may just build one out of cinder blocks... and have to rebuild parts of it from time to time.
