After a little more inspection, I think the friction I was feeling was coming from the DIAL LOCK clamp. The fixed side of that clamp was riding very close to the disk on which it is supposed to clamp when locking is desired. Also, I may have spun the lock knob just a little bit over time and could have had it very close to engaging that disk as well.
In any case, I moved the disk about 0.020" further away from the fixed side of that clamp and the KC knob seems to be fine now. Probably just operator error... :-( Thanks, Barry - N4BUQ On Fri, Oct 4, 2024 at 3:40 PM Barry Scott <[email protected]> wrote: > > Is there an "official" method of lubricating the bushings where the KC and MC > shafts extend through the spider-supports and their associated bushings? > > I thought there was an illustration somewhere in the manuals that shows where > the lubrication points are but I cannot seem to find that now.
