With the very hard jasp-ag I'm cutting, I have to use a dressing stick almost every time I use my 10" saw, all depending on the size of rocks I'm slabbing. I have 3, a very fine one that came with the Covington saw, medium 6" aluminum oxide bench grinder wheel from Lowes and coarse 60 grit blocks I purchased from JSGems. I'm using water & Lube Cool which is tough on the BD303 blade.

I had to dress the MK301 every 4-8 slabs, but the MK303c almost never needs dressing. But I just use an old grinding stone or a fire brick. Spending the money on a special dressing stick never seemed a good value.

Ive been using my dressiing stick on my nova wheel once in awhile but it didnt seem to do much for my sawblade but a fire brick worked great ..

A plain old piece of black obsidian will work too, but don't waste good obsidian.

Thanks! I've have in fact used obsidian, fire bricks, and old grinding wheels. If there's no advantage with the dressing block, I'll just stick to the other stuff.

Randy, the old grinding wheels work just fine. The 60 grit sticks will work faster but not necessarily better. I'm guessing Greg's dressing stick is the 200 grit I sent with his diamond belts. Those would be very mild for sintered saw blades.

I only have a tile saw, but I use fire brick as well as cinder block. Seems to work just fine, I can't really see any difference between the two, and busted cinder blocks are easy to come by.

I _rarely_ have to dress my 10" 303, but my old 18" notched Felker seems to need dressing every half dozen slabs or so. I've tried reversing the blade, but it doesn't seem to make much difference. I just cut into a 60 grit SiC wheel.
