Bench grinder tool rests

[Boatman53]

It's hard to see in that first pic but the CBN wheel actually has a slight crown to the face of it, so having the rest perfect isn't that critical. The crown is supposed to help prevent overheating the corners of the tool. Of course with the hand crank it is reduced even more. That CBN wheel can really remove some metal and was throwing it everywhere so last April when I brought it to a show I didn't want to be flinging metal bits on prospective customers.

I set mine up be positioning the rest in front of the grinder with something I knew was at the angle I wanted. Laid it on the tool rest and just adjusted the distance/angle until I got it where I wanted it. Trust me, if I can do it it can't be that difficult.

By positioning I mean when you screw the jig down to your bench or whatever the grinder is on, not the angle to the wheel. Altho that is pretty important too!

This is probably too late, but I have a hand grinder and made tool rests from James Krenov book - don't know which one.
Mine is really overkill but I'll take pics if yo are interested. I made two, one for plane irons the other for chisels, they work fine but as I'm laid up I have not been in the shop for awhile and all my chisels and plane irons are unused and sharp.
Krenov's rest had a nice thumb groove and I used a thin wedge to adjust angle.

I'd be interested in seeing pictures of your tool rests.

Thanks!

My 8" half-speed grinder uses straight 180- and 80 grit CBN wheels. The tool rest for each is the Tormek BGM-100, which is the same as the one on my Tormek 2000.

Both sides can use a blade holder or a flat plate. They can also use any of the Tormek lathe or knife jigs.

Adding my own questions to this thread, to keep the subject of tool rests all in one place.

I've got an older design of Delta wet wheel grinder, with a 10" x 2" (nominal dimensions) wheel.  The factory rest offers a flat platform with a wee miter gauge sliding in a slot.  This is better than nothing, but I find it tiring to hold a plane iron/chisel against the gauge and down at the same time - it always wants to slip out of place.  So I'm considering adapting the Lee Valley tool rest (pictured below) and grinding jig to my grinder.

I grind when I'm correcting flaws on a new-to-me tool's grind, or when the edge is chipped, so I'm often removing a decent amount of metal.  The Lee Valley jig clamps the plane iron/chisel in place, which means it will grind until the metal's gone, then just sit there.  Do you then loosen the clamp and nudge the iron/chisel forward a bit, repeating until done?

Second question is whether anyone's come up with clever solutions for grinding skewed irons/chisels on this jig.
