Yes I have on mine, but I have an open belt drive, I managed it without any mods to the mainshaft by making a long sleeve nut to hold the pulley on with the sleeve facing out. The rotor was bored to suit this and is retained by a bolt into the end of the sleeve. Instead of a key driving the rotor there is a peg in one of the pulley extracting holes which locates in a hole drilled in the rotor. This has been on something like 20 years and has not given the slightest trouble.
