Re: [TCML] Poly thickness

[Sfxneon@xxxxxxx]

Jay,
 
As long as there is enough sealer to fill in all the spaces between the  
turns, it should be sufficient. The main goal is to eliminate any air  between the 
windings and fill in all the voids. There's enough potential to  cause any 
air between the turns to ionize and greatly increase the chance of  puncturing 
the enamel coating on the wire. Building up a thicker coat will make  it more 
rugged and help protect the wire from bumps and scrapes. I applied three  coats 
of polyurethane to a dried 8" PVC pipe, wound the coil, and then applied  
seven more coats. This is more than needed, but it also makes for a good looking  
secondary.

All this talk of putting poly on coils has got me wondering (how many  coats 
of poly is enough)
i recently wound a 3" by 24" secondary with some  #28.  first i coated the 
form with 1 coat of poly.   then i wound  the coil.  Then I put on 4 more coats 
of poly.  is that enough? I  ha\ve not had any problems with it yet.
