I used 3/4" ply for my 3L series pulleys (3/8" wide belt).

To cut the v-section I mounted the plywood disk onto my tenon jig.  A tenon
jig rides in the table slot and holds stock perpendicular to the tablesaw
surface (see TenonJig.jpg).  The pulley blank needs to be mounted snuggly
enough so it doesn't move from side to side but loose enough so you can spin
it.  The saw blade is set to the correct angle and height for the v-section
your using (see PulleyJig.jpg).  You then advance the pulley blank into the
blade until it just starts to cut.  At this point, while holding the tenon
jig in place, rotate the blank 360 degrees into the blade.  Advance a little
more and repeat.  Once you get one side cut out, turn the pulley blank over
and repeat the sequence.

If you don't have a tenon jig one could be easily made out of scrap plywood.

That's my method for cutting plywood pulleys.

PS: Whenever you are doing any type of circular cutting on a tablesaw I
highly recommend a carbide tipped blade.
