Re: [TCML] secondary coil form

[Tesla <tesla@xxxxxxxxxxxxxxx>]

Hi

I've used PVC with success but as to price very dependant on where and how 
you find it, My first big piece was in a plumbers yard and I simply went in 
and said do you need that, $10 later I had a 12" by 60 inch piece
Plumbers and agricultural or roading  contracting can be a resource

Subject: [TCML] secondary coil form

Hey--

What does everybody use for a form for winding a secondary?  My
secondary was (note the past tense) wound on a cardboard tube as a
temporary measure, and as such things go, it has lasted for 20 years.
However, an errant spark traveled between the wire and the cardboard in
the little triangular air space between the end of the last paper turn
and the wire, and that was the end of a long and illustrious career.

The coil was 12 inches in diameter and 30 inches long, and I would like
to wind one about 10 to 12 inches dia by 36 inches long.  The obvious
choice is PVC pipe.  What is everybody's experience with PVC, and is
there something better in a reasonable price range?

Thanks much for the help.

---Carl
