[QUOTE="archive10, post: 885263"] On a recently acquired polar mount for a Prodelin dish, I have discovered Nylon-like bushings (or bearings, if you like). They are on the main pivot axis of the polar movement. See attached pictures. Question 1: Can/should I do anything to recondition / lubricate these? The original config is a separate bolt in each of the bearings (roughly , but only just so, aligned on the axis of swivel). I am considering stikcing a threaded bar through both, effectively giving an axis. Question 2: Would the threading on the rod dig into the nylon compared to the flat surface part of the bolts that were there before? (and even then one end had a third of the bushing "threaded", while the lower ones had all of it. The alternative would be to get a really long bolt, and use that instead of off-cut from threaded bar. Not sure it would be worth it though. Any advice from you mechanical experts is much appreciated. [/QUOTE]
