My lawn mower blades get dinged up real good by sticks and small rocks.
Grinding them takes me a long time, 2 blades, 4 edges.
Is there any reason why I couldn't set up the angle in the mill
and clean them up with an end mill?
I would think this would be a lot faster.
I could always grind in the final edge.

If this isn't a good idea, then everyone should forget I asked a stupid
question.

It will probably work, but I can't see it being fast.

Try an angle grinder and discs rather than a bench grinder. Works way
faster for me.

There's no need, or use, in getting every nick all the way out - you go
mow, there will be new nicks.

Belt grinder would probably also work faster.

I just use a file, doesn't heat up the steel, doesn't take _that_ long.

Well, yeah, if you sharpen the blade about once a week. ;-)
