Okay, pulling a Lazarus here, I am looking for a table feed gear for a standard 612. Part # 3529-A. It is the gear that goes on the shaft that mates to the rack on the upper table to move it back and forth. I've tried contacting several sources but one guy want more for the part than I paid for the machine (3 times actually). For that price I'd buy another machine, or make one. Unfortunately, I don't have the original so I would need some incite into the specs if anyone has one and can measure I'd really appreciate it. Of course if you had the part, for a reasonable cost, I'd appreciate that much more :-)
Failing this I'm probably going to have to replace the rack and gear with a set from McMaster Carr. Any help would be appreciated.
