burning off liners

Use a cupped wire brush on a cheap 4.5 in angle grinder. Take it to the bare metal. Angle grinders are cheap at Harbor Freight. Use paint stripper on outside of lid.

Also what is cheap is the $20 flamethrower from Harbor Freight. With afterburner engaged, 5000,000 BTUs @ 3000*F.



I use it to sear steaks after Sous Vide.

I'd do the angle grinder and cup brush for sure. Outside and fastened to a piece of plywood to keep it from dancing around too much on you. Should not take long. Wear appropriate PPE... don't go cheap on the brush- those wires that come off the brush head are moving freaky fast.

Hit it and see- you might have to step up to something a bit more aggressive. A sanding disc on the grinder might make more sense- and no bristles to contend with. My first UDS was a "food safe" drum. I'm sure my neighbors got a kick out of seeing me laying it flat on the drive way and scootching inside it - head and shoulders- to get the bottom section with a drill motor and sanding discs. That was all I had at the time. I have more tools now- but no interest in tackling another epoxy lined drum. Daddy says doing stuff like that "builds character" and he's probably right- but one was enuff.
