I like to sharpen by hand on DMT diamond stones, but when I need to regrind to repair a chip or change an angle I used a Worksharp 3000. However I find the flat grind the Worksharp produces is harder to hand sharpen/hone than a hollow grind. The only method I had to produce a hollow grind is my standard grinder (great for turning tools but too fast for chisels and plane irons. I also have a Jet slow speed wet grinder, a Tormek look-alike that is very slow and sloppy to use.
So I upgraded the Jet by removing the wet wheel and water sump and installed a 10" CBN wheel from Ken Rizza at Wood Turners Wonders. I went with the 600 grit that I worried would be a little slow - while certainly not as fast as my standard grinder, it is proving to be just perfect.
Here are some photos of my first test. I grabbed a very damaged chisel that was badly chipped and I brought it back to new in about 5 minutes
