Well it was time to clean my Powermatic 64A table saw interior and grease the worm gears. Time consuming but necessary to say the least. I started to notice my turn crank began getting hard to turn when approaching 35° thru 45°. I took a small brass brush and cleaned all the worm gear teeth. The teeth were caked with saw dust…I suspect this was the culprit for the hard turning. After a good brushing a shop vac cleaning and a good greasing with Rig Grease I decided to use my new digital angle gauge to reset both stops. I was able to set the 45° exactly were it needed to be at 90° to my fence. Couple small adjustments. Once putting everthing back together I cut a test piece at 45°…put it to a square

I wonder if graphite dry lube would work in place of grease without catching sawdust.

I use paraffin wax dissolved in solvent (the options are abundant) to lube everything under the hood on my Unisaw and don’t have any issues attracting dust. A blow gun while the DC is running cleans everything quite well and reapplication takes no time at all only a few times per year.

If you used grease… be prepared to do the whole procedure over again pretty soon. Wax or a dry lube is what you want as it won’t attract sawdust or accumulate gunk.

pretty much how i clean my uni saw, long tube air blower gets into all the spots, sure wished it had better dust pick up, lol, have taped and sealed every orafice in the dang thing, did help, but still a gaggle of it on top.

i used graphite a few times, but last time did the parafin wax the ole gal uses in her canning, hehe, if only she knew
sure is a pleasure to turn when lubed correctly

No heat needed. You can rub it on straight from the block, or you can shave off flakes and dissolve in mineral spirits. For those who don’t have it, you can pick up a pound of it at the local super market, walmart, hardware store, Amazon, etc… for about $2:

I use it both ways. For the dissolved stuff, a mason jar works great, and a small wire basket makes it easy to dunk small parts like nuts and bolts. Gets wax where you otherwise can’t normally get it. Pop it in the refrigerator for a bit and it will turn into a paste.

Cheers,
Brad

Sure would like to know how much paraffin to what amount of mineral spirits to make the mixture if someone doesn’t mind telling. Do you brush it, drip it or spray it on?

Yes :)

Brush, wipe, drip, dunk, spray, whatever it takes.

I’ve got a couple cans of dry lube and have tried it quite a bit on various machine parts. To me, it just doesn’t seem to be as good a lube as more traditional stuff, you need to use quite a bit more than what I expected, and doesn’t seem to last very long. YMMV.

Cheers,
Brad

I use furniture paste wax instead of parrafin – harder than parrafin once dry. I find it lasts longer.
