Hi Kent!

  For most purposes, lexan works great as a rotor material.  I've used 1/4"
lexan with 3/4" long 10/32 studs (nuts on each side of the disc) up to a few
kva without any ill effect.  For a seriously powerful coil, I'd insist on
G-10 or GP03 (just as good and usually cheaper), maybe 3/8".  I have a 1/2"
GP03 disc 11" in diameter and it weighs a ton.    If you're just running
15/60, lexan will work fine.
