Assuming you have lubed the shims of course, is this lower noise than the rollers of the needle bearing you removed...and is it sustainable over time? (the lube won't gum up)?? If the rollers were poor quality and out of round maybe you are in better shape.? They do sell bearings of a range of quality and cost.

Reminds me that...the original Meade LXD55 mount had lubed shims and no bearings.? Later in the LXD75 they put in bearings.? They didn't go back to shims on layer mounts!??

I'm having a discussion with Chip about the position of the upper cylindrical needle bearing in the GM8 and G11.? The lower needle bearing is all the way at the bottom near the clutch knob.? But the upper cylindrical needle bearing is 2 inches below the top.? That gives torque on the the 1.25 inch shafts, and it also torques the body of the RA and Dec sleeves.? Chip has shown me a photo where someone put in a 2nd upper needle cylindrical bearing...I think this idea might be a good one.? Anyone tried that or read about it?

Best,
