Wish you'd stop being so good to me captain
How low do you file your rakers? people need to learn how much the cutter actually contacts the wood.
Hook comes from tilt, not depth. Sharpen the cutter then back it away and clean out the gullet.
It’ll work but won’t be as sharp as a hand filed chain because as stated, you’re losing the “hollow ground”. Your better off backing the wheel off a hair after sharpening the cutter so it doesn’t contact the area the cutter actually contacts the wood if that’s what you’re after. Also every time you switch between touching up with a file and grinding, you’re wasting cutter length.If you don't get the wheel low enough you won't have any hook . The OP has his grinder set up perfect with good hook on the side of the tooth. . I've had chains come to me wouldn't cut following 0regons directions with no hook on the side plate. Steve

To each his own.
Philbert adapted those images from one in the Oregon manual, but they are his. What would Oregon know? They only invented this chain 75 years ago, and probably have more than a million man-hours in research, testing, etc.Philberts images are just coming from the Oregon manual (which I threw away after reading that bs} Oregon is just worried about liability in that manual not wanting a aggressive chain that actually cuts.

Why does square ground chain cut faster, the cutters are the same as getting the wheel low enough so the side of the wheel hits the face of the tooth.
If you don't get the wheel low enough you won't have any hook .
There is no way your going to hollow grind a chain with with a whee . . .If your hollow grind is so important why do square grind chains cut faster.
Of course they are 'exaggerated': they are illustrations to make a point that is hard to see.. . . you are exaggerating your diagrams a LOT on the top 2 again.
This is a chain I sharpened today, experimenting with a few different grinders: 511A, 'clone', and even HF (trying some new wheels). The exact profiles may vary with the wheel diameter, wheel thickness, wheel edge profile, and grinder geometry (what point of the wheel circumference touches the cutter).As I said you are not going to get a hollow ground tooth from a grinding wheel . . .
Grinding wheel is set just like in my illustrations. I blend it into the gullet with second pass(s) to eliminate any sharp points. Again, see how the file fits.Your getting your grinding wheel quite a bit lower than what the oregon directions say, almost like the OP. With those directions you'll end up little or no hook on the side plate resulting in chain that wont cut good. Steve
Yes.I assume by hook you all mean this shape?
Yeah, I think it had both chisel types, didn't it?I like those models. The old version had a couple of links.

Welcome to A.S.!Do you clean your chains before grinding? If so what do you clean them in. Currently i just blow them off with air
Brake clean , works well degreases the chain so bar oil does not contaminate your cutting stone .Do you clean your chains before grinding? If so what do you clean them in. Currently i just blow them off with air
