Having worked with inexpensive (cheap) rotary tables I have found if I put gentle tension on the clamp, and only approach each position from eh same direction of rotation I get pretty good results.  That's a little trickier when milling radius parts, but not impossible.  You just have to think about it for a minute.

I thought about that job for hours, while trying other ways to clamp and index the nut plate. I have a Sherline 4-jaw on a 5C mount but the collet keyway isn't quite aligned with a jaw, so the plate came up angled in a hex collet fixture. A B&S-0 indexer with chuck is too tall for my mill when upright. The rotary table takes an MT2 collet, which held the shank of a broken endmill as a locating pin for the drilled plate and the mill spindle.
The rotary table was missing its clamp lever, for which I had substituted a 10-32 screw. Last night I realized I had only been tightening it until the screw hurt my hand, so I sleeved the screw and now tighten it enough to hold.
