Got it cleaned and deburred. It could use some work to make it smoother to operate. Putting thrust bearings behind the handles would help immensely. Just like the compound on a mini lathe. Fairly smooth in one direction but tight in the other direction. The acme screw for the vise jaw could use to be replaced. It's very sloppy and roughly made. It's a rare beast though at 5/8-4 thread. I couldn't find that combination anywhere. 5/8-6 is the coarsest I found. I could attempt to make one using the mini lathe but I'm not sure if it's up to the loads that would be put on it.
