RE: [TCML] I think I ruined my 6" secondary.



Kris,
     My 6-in 22 AWG secondary has bugs, sand, bird crap, dust, water vapor, you name it, in the polyurethane coating.  It lives outside in the sun, rain, and snow.  I have not had a catastrophic failure except when I abused the coupling, and then only the bottom turn was damaged.  Just try it!

There were a few turns that were a little loose, but over all, turned out pretty damn good for not building a jig. I started coating it with poly and once I got about 10 coats on it I noticed it was kind of getting a little rough from dust and whatnot, so I grabbed a piece of 400 grit sand paper and gave it a light once over and began coating it again. Thats when I noticed that I had sanded the insulation off in some spots on a few of the loose turns. There are maybe 3 or 4 of these spots on the bottom of the coil and 4 or 5 spots in random places along the entire length. I was so bummed about it that I shelved the project and haven't given it much thought since.

I was hoping to put around 4KVA through it. Has this ever happened to anyone else? Is this secondary salvageable or should I scrap it and save up for another acrylic form and a new spool of 22 gauge (might be awhile, I'm broke at the moment)?  Any suggestions?
