I have a 4" rotary table I purchased from Little Machine Shop a number of years ago. They still carry it, part# 1810. I have run into a problem regarding adjusting the backlash. Till now I haven't found it necessary to adjust the backlash so that portion of the mechanism hasn't been touched.
According to the user's guide I found on their web site, it's done by loosening the two set screws on the side of the table nearest the hand wheel, then the vernier "color" (I assume they mean "collar") is rotated slightly counterclockwise to reduce the backlash. I assume there's an eccentric hole in there so the clearance between the gears can be adjusted.
The problem is that I can't move the vernier collar after I loosen the set screws. Is it usually in there pretty tight, or is something else going on? Hardened grease? Any suggestions on how to loosen it up? I don't want to damage it -- I also got the tail stock and dividing plates for a very good price by today's standards so it would be a real shame to screw it up....
