from what i understand, the plate closer to the bearing is fixed to the ra shaft and does not move. YES, so is the other plate, snugly pushed up to the face of the worm and then LOCKED forever to the RA shaft too.
so by tightening the bolts on the other side, you're pressing the cork onto the worm wheel? Not quite, pressing on a floating plate of PVC which then presses on the cork.
do you have anything preventing the bolt going through the cork As above
did you machine the shaft collars and the plate? yes
i presume you only need to get the bolts tensioned right, and then you don't need to adjust them at all? Just pushing the collar up snugly then locking it is enough for me to be
able to move the scope (well balanced) around and it stays where I leave it...acts like a good friction brake.
when you loosen the bolts, does the worm wheel move axially at all, as then it would misalign with the worm? No play what so ever...snug as
is the worm wheel on a bearing on the shaft? No, just a very close tolerance fit.
