How about a single pass using a UV curing coating?

I didn't see that in Mcmaster or Enco.
Is that something I can pick up easily & cheaply?
I DAGS on '"uv curing" coating' but didn't come up
with a retail outlet. Suggestions?

What do you need to make that can't use a tapewound core?

Envision a really long 'E' core.
I want a lot of flux concentrated between the center pole
piece and the two outer pole pieces. Figure ca 10" long
with a 1" diameter center pole.


Thanks!
