My big compressor has a couple of pinholes in the bottom of the tank, no doubt caused by the previous owner not getting the water out. It’s a good solid machine that runs well so I’m reluctant to replace it. I’m thinking I could grind the holes back(they’re tiny at present) to some better material and then plug weld them or put a patch over? Is this feasible? It would definitely be cheaper than replacing the tank or building one. Or is there a way I could use an existing pressure vessel and modify it to suit? The tank is about 200 litre size.
