Hi Bill,
The pulleys and belt came from a local (Victoria) company P.I.E.S.
They have them in stock.
I used 2.5mm pitch 15 tooth for the motor and 60 tooth for the worm.
The belt was 200mm long.
The pulleys need to be drilled to fit. 5mm for the motor and 12mm for the worm. It's better to do these in a lathe and use a reamer to make an exact hole. You want the holes as exact as possible because they will add to the final PE.

Cheers,
Luke
