Most motorized shop "grinders" run at a motor speed of 3750rpm, seems that's how the motor was designed. Dedicated grinders for sharpening rarely run faster than 1750rpm. In either case, you can cook the temper out of a tool edge in the blink of an eye. Sheets of flying sparks will be small comfort.
But, if you go slow and are careful, it is possible to rough out the shape of a tool.
I am a sucker for pairs of skew chisels in wood carving. My first pair of NAREX (Lee Valley) 1/2" skews come from the CZ factory at 25 degrees. By hand, I scrubbed them back to 20 and made them carving sharp. They are so good, I bought pair #2 within 10 days!
I decided that I needed another carver's stop chisel. This is double beveled, 10 degrees each side, for a total of 20. So, I used the high-speed grinder to take off the entire end of a Narex skew = squared it off. Then I established the 10 degree bevel on each face. Then, by hand, I went from oil stones to water stones to my strop. I got a 1/12 stop chisel which is the answer to my wishes. Very good steel.
I don't know how fast you can pedal this thing, especially a small stone with a low rim-speed. Going to take a very long time to get anything done. If it was a really big/old-fashioned wheel that you had in mind, for light work it would be a thrill to use. Then you could apply to the Grim Reaper and get a part time job sharpening his scythe!
