Thanks Bob. I’m using a nylon tipped 10-32 set screw.

Is the nylon tip mushroomed out, or too large diameter? The only problem it sounds like you're having is with the action of that knob. Maybe the thread is metric and not 10-32, giving you a false "tight" position?

Once I tighten, top stage doesn’t move.
