I ASSUMED the lubrication on the rail and ring base clamp was to allow the parts to slide into a tight fitting position rather than have friction cause the fastener to reach specified torque without the pieces having slid into full lock up position.
I must have missed the part about floating and return to zero.
I think there likely is some validity to lubricant allowing the anodized aluminum or parkerized steel wedge clamp pieces to move into their ultimate lock up position without galling or deforming parts.
But, I don’t lube such wedge clamps and am blissfully unaware of experiencing issues caused by not lubricating them.
