10 K is only internal grinding. External is about 4 kAt 10k rpm, you need a guard on the wheel too.

Never be afraid to post anything, even if it is something small.With all the fine projects posted by Mark (and others), I'd be embarrassed to post something from my garage
Nothing half done, very professional in every detail
I think for all the longer it runs at a time, cooling will not be a problem. I will be checking this and if needed I could add a small fan, but I don't think there will be a problem.Mark- looking very sharp. Question: Will the motor cover create a cooling problem? Do you need a fan or heat sink with that? Just something to consider.

I think you are basically correct, but I think there is a "friction" ( for lack of a better word) difference. Going the same direction, the higher speed (in my mind ) pulls the lower speed device. I assume this could affect the finish. I may all all wet here though. I figure that is why opposite directions would be better.Logically the direction of the wheel against the work should be opposite to each other to get a higher differential between them but in reality isnt the speed of the grinding wheel so far above the speed of the workpiece that it wont make much difference?
