Polishing Lexan or Plexiglass



Original poster: "Mark Broker by way of Terry Fritz <teslalist-at-qwest-dot-net>" <mbroker-at-thegeekgroup-dot-org>

After much thinking and internal debate, I decided to make my next TC 
primary base out of 1/2" thick Lexan and the primary winding supports out 
of 1/4" lexan.  The base will be 18" in diameter, there will be 6 radial 
supports for the primary winding (about 13 turns of 3/16" copper tubing).
(3.5"x 18" secondary with 28AWG, 12/60 input, sync triggered gap, GeekCap, 
FWIW)  I'm wondering if there is any way to polish the edges to 
reduce/remove machining marks from the Lexan.  I have only attempted fire 
polishing with a blow torch once, and the results were abysmal. :/

Thanks,
