Rob,

Ah now, that is the rub.

I had to work it out so that the plastic would not burn or melt when
held against the wheel for a couple of seconds without moving the key. 
If I were still at the university I could tell you, but since I no
longjer have access to that machine I cannot tell you the motor speed or
the pulley diameters to work out the speed.  Sorry.f

Newer plastics tend top take heat a little better than older plastics.

Try a reduction from 1700 to about 1000 or 900 rpms.
