Thank you so much for your reply. I ended up breaking it down completely and found my issue was that the center pin upon which the top plate rotated on had migrated to far up and no longer acted as an axle for the base. While I'm glad I had an opportunity to disassemble clean and re-grease this awesome base, a simply tap tap tap down upon that pin in the middle would have solved my immediate troubles. I'm being verbose not necessary for you but for those that come after us with the same problems. These bases are mosters and I would not be surprised if I find them still installed 30 years from now. The guy simply built them to last.

@MartinB I see you are staff and assume still active on the forum? You had posted about this wedge which I also have enjoyed for many years. I recently brought it out after over 2 years hiatus to remount my SCT and can’t figure out why it is moving a degree of so left and right, even after bolting down (not sure exactly same bolts) and t/nut has no play to explain it (horizontal fin knob t/nut. Do you remember if you encountered any simular difficulty? Mine is on a meade tripod.)
