I'm restoring a vintage Powermatic drill press and have run into a problem. One of it's variable speed pulleys has a worn keyway. One solution we came up with was to rebroach it to 7/16". I'd post pics but the parts are at a machine shop now. The difficulty I've run into is my machinsist (two man operation) doesn't have a 7/16" broach. His Dumont Minuteman set only goes to 3/8". Dave McCann suggested I find machinist who uses newer wire cut technology. Before I take that more expensive route I thought I'd see if any of you machinists have a 7/16" keyway broach with a 1 3/8" bushing I could borrow for one keyway. It may be a long shot but I figure it's worth a try before I go shopping for another machinist since this guy is reasonable and will take walk-ins unlike the rest of the machinists around here that work for Gov big dollar missile contracts.
Thanks.
