E-mailed John.

Will see what he says/suggests.

Thanks everyone!

O.K. John advised to dress the stone to get the paint off. Says he has seen that before.

Didn't have a dressing stone, brick, whatever so just cut another slice off a rock.
Took about 30 minutes going really slow but it took off most of the red paint on
the sides of the blade and, I gather, the edge.

Cut another slice and it worked fine. Cut good and no jamming.

Thanks again everyone for all the help.

Glad that worked but I am concerned about your report of arbor stops and motor still turning.  Only way that can happen is if the arbor adapter is loose on the shaft.  It should have an allen screw to lock it down.  Make sure it is tight.  The message you sent me indicated motor turning but blade stopped.  That sounded like blade nut too loose.  Or is it a case of motor and blade stopped turning but motor still making noise?

The arbor did stop, but the nut was tight. So the motor must have stopped turning and just kept humming. Is fine now.

On  the subject of blades, I was at the Franklin, NC show this weekend and manufacturer, Highland Park was there displaying their saws and other equipment.  Having an 18" Highland Park from the 60's I was curious to see how the quality compared. I was extremely impressed. In the side of the booth I noticed some Chinese made very heavy duty blades. I purchased a 24" blade for $150.00 on faith after seeing how everything else was made. I have both Covington and original Highland park saws in everything from 10" up and I know quality when it comes to saws. I would not hesitate to recommend any of the equipment from Highland Park.

We also took a shot on a Chinese 14" blade at Quartzsite a couple of years ago. It worked so well we bought another on our next trip there. Can't say who made it offhand, but it was a good deal.
