New to me Cincinnati Toolmaster 1B post 1961 model. Bought it without seeing it in person, pictures showed a decent machine with “honest” use. Not a “Navy” model in that it sported its original coat or maybe second coat of paint not 10 or more. I was looking for this in a used mill. It made the trip from NE coast to Montana upright and without getting hit with a lift or anything or rather, anything that hurt it.
Just got it running had it for a little over week cleaning and checking it out. Opened the power down feed and the gears do not look warn at all, same for the x feed gearing. I replaced the outer seal for the clutch knob was able to cross it from the original CR number to a National 50151S.
Drained and refilled the x table drive discovered a leak, the outer bearing from the motor input side was shot replace it SKF 62052-2RSJ and a 6201-2RSJ, only the 205 needed replacing, it is shielded and acts as the oil seal. Running nice and quietly as does the spindle.
I will need to replace the spindle seal at some point and look at the jack shaft idler as the manual is correct about too tight more noise, but it looks a little warn but it’s making chips.
This is really a pleasure to work on, clean the gunk out of the Allen heads and break them loose and unscrew them by hand, perfect threads. The covers I have had off the fit is just amazing. The people that made this were true craftsmen, 60 years later I’m looking what they built in total awe at the skill and dedication to their craft to produce this thing.
I have some pretty good pictures of what the insides of the feed drives look like and will post later.
