I got a good price on my toolmaster years ago as the feed box on the power feeds were broken fortunately in my case the gear shaft broke not the gears so I simply bored out the shaft from the gear and made new shafts. No chance you are as lucky?
The problem with the machine is if the the trips for the power feed aren't st right you go crashing into the table with 1/3hp of force, so this seems to be a common issues. At the same time I must admit perhaps using a variable feed on the Bridgeport has me spoiled but I am wondering if it may be better to retrofit a bport style power feed with varispeed? I am pretty sure it would have the power. It is so nice to just dial it in till the cutter is running nicely as opposed to the traditional shifter gearbox on the toolmaster. I think if my feeds were trashed I would think of doing things differently than going thru the effort of fixing them.
