My "biggest task" for the grinder, is to put a 3" camber on a plane

Japanese 250 grit waterstone. It has quite an appetite 8-)

Failing that, the big wet wheel.

I just don't get these "half speed" white & pink wheel grinders.
They're probably great for HSS and turning tools, but for something

especially if laminated) they're still going to be too fast & too hot.
