Scott,
Wow, brain waves as was just going to give my 2 cents of Plexy. All my
coils are plexy, and spend many hours drilling, tapping and cutting
plexy. Spending a few extra $ for bits and blades is worth the cost. Cut
slow, drill slow, use H2O for a lube and the finish product will be
outstanding, Plexy sure makes nice coils indeed. The end process is to
take a torch (propane) and round the edges of the cuts, warning this
takes aptitude as to much heat and you have a burning mess.   Now
building control units out of plexy @

Scott,

I have a local plastics supplier that makes custom golf car 
windshields for us out of acrylic.  He actually makes lots of custom 
products out of acrylic.  They use a special set up with a small 
torch running on hydrogen / oxygen to finish all the cut 
edges.  Looks beautiful.  The idea of the H / O is to have no soot 
deposited on the material.  The torch head is mounted in a fixture so 
the worker just slides the material past it.  The rate of travel of 
the material controls how much heat the acrylic gets.
