Quote:I took apart a Vixen GP and it also had bushings.I would not consider this to be "bad design" - Ed Thomas can probably weigh in here but well-made bushings would probably outperform poorly-made bearings (like those in the China mounts).This is also why you've got a lot of folks replacing the bearings in their China mounts with Timken or SKF bearings.I had thought about replacing the main declination bushing with a large bearing - but it would require massive machining and destroy the value of the AP600 as an antique / collectible.There used to be a long waiting list on AP600's - I can imagine Wally toiling at the mill / lathe making each of these by hand without benefit of CNC
