pWhile I'm waiting on the bearings, on to other things. My new belts and speed control quadrant arrived today, so I swapped it out. Also cleaned up and de rusted the metal parts of the saw guard.

New and old

Of interest to 'us' is the fit of the new quadrant on the roll pin pivot and the clearance between the new quadrant and the legs the pivot pin is mounted to. A pix showing the alignment of the worm gear to the quadrant gear also. Might prevent reoccurence of that wear.

Resist the temptation to force the speed adjustment towards slow and it may stay that well aligned.

Earlier in this thread JPG recommended the Bill Mayo speed control improvement. Yes! It addresses a couple of things on the speed control to strengthen it and reduce wear. In your pic, I've circled one of the wear points as an example. Over time the hole in the legs sometimes gets enlarged by the reaming action of the spring tension (aka roll) pin being used as a hinge pin. Once there is wear in those holes the quadrant/porkchop can wobble a bit, accelerating the wear on both the gear and the holes.

The Bill Mayo improvement deletes the roll pin and replaces it with a screw. The quadrant rotates on the hinge pin rather than the pin rotating with the quadrant, and it strengthens the legs by tying them together. I've used a variant of it (larger screw or bolt) to save a speed control assembly that was junk because the highlighted holes were so enlarged.

Some house stuff pulled me away, but I'm back at it. While waiting for new bearings for the power shaft and quill, I started in on the jointer.

The knives cleaned up great. No nicks either.

John,

It looks like you have gotten a good start on the Jointer. The rust looks like lighter surface rust only so it should clean up very well. Once the rust is removed, the bare metal is clean and any painting is done use that good ol' Johnsons Original Formula Paste Wax or similar to protect the bare metal. Do that before re-assembling the Jointer to get those spots that will be harder to protect once the Jointer is re-assembled. Wax on the contact surfaces between the Base/Outfeed Table and the Infeed Table will protect and provide lubrication there just as is desired on other surfaces having moving parts on them like the Way Tubes on a Mark V. Do make sure there isn't any paint on those surfaces. The Cutter Head can be waxed too including into the blade recesses. The knives are tapered and the wedges will hold them in even with the surface waxed. The benefit is rust protection.

The cleanup on the knives looks great but do sharpen them before using them.

Thanks Russ, that was my plan, I'm just happy the knives aren't all nicked up. looking forward to starting to put this thing back together. Bearings are slated to arrive Friday.
