stone grit for sharpening jointer blade

[bnlsrv]

Having read the book, and planer / jointer jig instructions I don't see what grit the stone should be at when I sharpen my jointer blade. Anyone know?

You will almost undoubtedly need the fast cut (220).  Do all three blades, then grade the stone and do all three blades again at the fine cut.
