Interesting thing. 22 mm metric shaft come out to 0.870. Now if I
had a lathe that worked I could bore out the pulley 5 mill and use a
7/8 shaft US motor.

Or you could take that US motor with its .875 shaft, clamp it down, turn
it on, & apply a file to the rotating shaft. .0025 from the radius
should be a piece of cake.
