Re: [TCML] Spark gap assembly, acrylic?? and toroid size

Hi Gary,

I didn't have much problem tapping UHMW PE, except there's a lot of friction 
on the tap.  Same with acyrlic.  Ive seen taps actually melt the plastic 
when tapping.

I guess I wrote from a machinist's perspective.  Very soft plastics like 
polyethylene cannot easily be machined to a high tolerance in the same manor 
as say Lexan or Delrin.  It's not to say that it cannot be cut or drilled, 
just that it won't come out as nice.  Tapping is also likely to be a 
problem.
