FINALLY have (almost) everything for my UDS. Found a seller in Toledo with drums for $10. He said they were filled with water-soluble catalyst that was in a plastic bag in the drum. I inspected several and none of them had liners, just nice, clean steel.
Found a sheet metal shop that had spare expanded metal they cut to size for me for $10. Have the basket built. Will start working on the barrel later this week. Should be able to burn it out Saturday while I replace a section of my roof.
Chargriller Super Pro w/SFB, UDS (Wish I'd made this one sooner)
