"What is really disturbing is new B&W coil stock at 1 3/4 inches in diameter with many turns per inch, which would be used to re-coil a 80 meter and 160 meter coil base, sells for $80 for a 4 inch long piece from B&W direct!  The price is insane.  I think I can make my own coil stock for the high bands which have few turns per inch but close wound ones for 80 and 160 meters might be a real challange to make myself."

How much demand is there for B&W coil stock these days?  Welcome to the world of supply and demand.  Statospherically high prices on many specialty items have certainly dissuaded me from attempting many otherwise appealing projects.

A friend of mine made PA tank coil forms for his BC-610 by threading ABS (not PVC) pipe of appropriate diameter on a lathe. It was an easy matter to then wind the wire into the threads.  This worked out well in operation with no undue heating of the finished coil.

My friend is lucky in that "his" lathe runs on beer. (He tossed a six pack in the direction of his lathe-owning buddy).
