I have two Sorby oval skew chisels. But, I can not figure out a

I have the woodcraft slow speed grinder and the wolverine grinding jigs.
But, the wolverine skew jig gives a concave grind. I am looking for a flat
grind.
Any suggestions for fast & consistent would be greatly appreciated.

I sharpen mine by hand on a piece of sandpaper.

I use scraps from a used industrial belt sander (about 3 feet wide).
Hold it flat on a bench with one hand. Use the other hand to hold the
skew. Place it so the bevel is flat on the paper and let your knuckles
rub along the bench as a guide.

This is much like sharpening a carpenters chisel on an oilstone, except
you don't have the oil mess to contend with, nor do you have to worry
about keeping the oilstone flat.

If you find that the bevel gets too short, use the grinder to take away
the heel of the bevel then hone on the sandpaper.
