From the serial plate it's a Model 510 and the S/N indicates a 1986 model. This unit was used by the USAF on Seymore Johnson Air Force Base and then auctioned off at a DRMO auction 8 years ago. The gentlemen I bought it from is still stationed there and bought it via silent auction. He never used it even once.
Missing some key items ... power coupler is broken, no lathe chuck or tools, no sanding disc, and missing the jointer fence.
The seller told me that it ran, but ran "slow". After I got it home, I rotated it manually from the high end to the low end of the speed range, plugged it in and she purrs. I've oiled both sheave sets and sprayed silicon on the rack/pinion for the speed changer -- per the sawdust sessions mentioned in the "newbie" sticky post.
Aside from the missing parts, I have 3 issues I need to resolve, at least that I'm aware of, both with the headstock.
1) First, I've probably started this thing 20 times in the past 2 days and never changed speeds without it on or manually rotation, but on occasion it has started up "slow", sounds like binding somewhere, rotating no more than a few revolutions per second at best, maybe slower -- when this happens I of course turn it off immdiately, and if I manually rotate and bring it to the slow end of the speed spectrum then turn it on, it runs at normal speed and I can spin it up and down through the speed ranges and it works like normal. Any ideas? Speed changer feels very good after the sheave oiling and rack/pinion cleaning / oiling. I don't want to burn up the motor, would be good to isolate what this is and resolve ASAP.
2) Second, the quill is very hard to move in and out. I've removed it, cleaned it, and reinserted per the sawdust sessions. But the set screw keyway seems to have a high spot on one side that is gouging the cast aluminum of the headstock. Should I purchase a new quill or is there a way to fix this one without taking it to a machine shop? Photos are attached.
3) The spline gear in the quill, if the quill is sitting on a flat surface and I spin the chuck end which spins the spline end, the spline is very clearly, very slightly bent, you can see it wobble just a little but very clearly. Is this expected? I have a video of this in action, not sure if I can post the video to the forum though.
Anyways, I've found tons of great info on how to clean, use, and maintain this machine on this forum just in the past few days -- just wanted to say what a great help it's been for a SS newbie like myself.
And now to the photos ...
