[Elecraft] OT - Source for Air Variable Capacitors

There is a Canadian Ham on the magnetic loop list who makes first class 
butterfly caps(you assemble) less than $100 to my home.

If you are making a home-brew loop why not make the capacitor too?    My 
loop works fine at 100 W input but not yet tested at 500 W.  I borrowed the 
capacitor design concept but the implementation details are mine.  Capacitor 
components are hardware store copper pipe, copper pipe couplers, and PEX 
tube.
