I just acquired a Servo small drill press. These are really nice variable speed precision drills, with a dila indicator depth readout.
Unfortunately, mine was a bit abused, and I'm in the process of fixing it up. The downfeed lever screws into a hub that is on the end of the pinion shaft. In theory, the hub is only held in place by the pressure of the lever being used as an oversized setscrew. Mine is stuck on firmly, and the handle has been used loose, which has wallowed out the threads in the hub. I'm ordering a new hub, but I need to get the old one off. My biggest fear is that some nitwit epoxied in on, although I can't see anything suspicious.
I am going to try some Kroil, but I suspect I may have to apply some force to get the old hub off. The easiest way to avoid putting any force on any of the internal gears or bearings is to cut/grind a couple grooves in the sides of the hub, and use a small 2-arm gearpuller to pop it off.
The hub is about an inch in diameter, and the end of the shaft is about a quarter of an inch. Most "small" gear puller all seem to be a bit too big. There also seem to be a lot of small specialized pullers for "armature bearings", and "Pittman Arms", but many don't really indicate how big they are. A lot of pullers are rated by tonage, and I'd guess1/2 ton would be plenty, but they don't seme to come that small.
For example, this one looks lovely:
Anyone got a likely device they can recommend? I can always build something, but I have enough projects piled up as it is.
