Went out to the shed and checked the new/old saws blade height adjuster after it soaked in PB Blaster overnight. At least 75% improvement in cranking torque of dial. The arbor pivot pin for this function is a light press fit thru the casting, so while it can move easily enough, no slack. Would need to fully disassemble the mechanism to drill holes to allow lube in, drill and tap for a grease gun, or to press the shaft out and clean/polish the affected surfaces. While having a way to lube it seems like a no-brainer they don't do that in fear of it collecting dust. I suppose could drill & tap so could connect grease gun hose and run them thru the side of the box. Give it a squirt once every six months or so. I mean, the design makes it so it's nearly impossible to get grease or even a fluid to the pivot.
