Greg:

IN THE BEGINNING I read everything there was to read about preparing a coil
form and then decided not to follow them.

I washed the 6"x48 piece of white 1/8" PVC using a sink cleaner like
Comet/Ajax then gave it a light sanding. Dried it in the sun. Cleaned the
inside too.
No baking/broiling, poly etc.

I wound the wire from Parawire then applied a 2 part epoxy to seal it.
All is well after many hours of wonderful sparking at 900 watts for the past
2.5 years.

Remember, get 10 coilers together, ask one question...you'll get 11
different answers and likely all will be correct.  :))

Safety First

Hello all,

Some coil plans I have say that when using PVC as a coil form, it should
be coated with polyurethane (or similar) BEFORE winding the wire on to
reduce losses. Is this really necessary? I would have thought it just
adds more loss by making the form wall thicker.
