I had a horror show of a time for a while. I switched to .28 wire and I use the cigarette paper method. Works like a charm. Much better then the drill bit method IMO. Plus I get to burn paper too, which is just awesome. I spent last night cleaning a rolled mesh in water, 1 minute or less, then torching it, about 1 minute, wrap with cigarette paper, 1 minute, install in empty Birkshire ATTY, wrap coil. Adjust, burn off paper. About 10 minutes. No issues, works like a charm.
