I'm considering buying an 80 grit Norton SG grinding wheel form Craft Supplies. It is fairy expensive; am I being sedcued by the marketing literature, or will it really be the last wheel I'm likely to ever buy and put a smooth edge on my gouges forevermore? I invested in a Woodcut Tru-grind jig and that has been a remarkable improvement (over freehand sharpening. I suppose anything controlled would be better for the amateur).
Anybody have any experience with the SG grinding wheel? Thanks

Regardless of what grinding wheel you buy, it will NOT last forever. Personally, I go thru a pair of 8" grinding wheels every 6 to
8 months. Yes, I dress them often and consider them a consumable item.Peter Teubel Milford, MA
I have one of those cheap, white, made-in-China grinding wheels that came on my Delta slow-speed grinder. It burns high speed steel tools a whole lot quicker than the cheap, gray, made-in-China grinding wheel on the other side of my grinder. No matter how briefly I keep these wheels before I replace them with better ones........its gonna seem like a whole lot longer. Go ahead and buy that good Norton SG wheel and enjoy it for the rest of your life. Or, go cheap like me and hate 'em for as long as you can stand it.

No experience, but consider the following quote from "The Complete Guide to Sharpening" by Leonard Lee:
"Norton recommends this seeded-gel stone for use only where sufficient grinding pressure will be used to ensure particle fracture; it is not for light cuts and is too hot for carbon steel. Used for grinding the bsic shape on HSS tools , though, it is ideal."
The wheel referred to here is the 5SG60KVS used by Jerry Glaser.
This is from the 1995 edition, so some things may have changed. These wheels have intrigued me for quite some time, so if anyone has a different take, let me know.

Back in December, I got some of these wheels. I got them from Packard Supply. Same item, just cheaper. Packard are really nice people to work with. Really nice wheels.
FYI... My local tool store can these. But in order to get the price down to even close to mail order, I'd have to order 20 wheels.
