Gday Evan
Meade has no such thing as a 3 star align with the LX200s.
A 2 star align will create a very simple pointing model
( inAltAz, it is equivalent to faking the lat and long to get a ground to sky conversion )
Doing synchs merely resets an internal encoder offset, ie it affects the entire sky model, so if necessary, on slewing to a new area, goto a bright star and centre then synch. You are good to go for that whole region.
As to the RA knob, its not threaded at the top, its a simple axle with grubscrew at the top.
Have attached piccy of it diassembled.
Maybe find a bolt you can cut down and use that to get a better grip,
or mark the position, then just unscrew the bolt fully and file a small flat onto it in the reqd spot
