Re: PVC Pipe - Plastic Wrap Coating

Original poster: Terry Fritz <teslalist@xxxxxxxxxxxxxxxxxxxxxxx>

Hi Dave,

I don't "paint" my coils anymore either ;-) I do wind them "tight" so minor temp/humidity variations do not cause the windings to go loose and fall. But for protection, I wrap them good with shipping stretch wrap. All office supply stores have it. It is like Saran wrap but heavier. It protect the coil from physical damage very well and if it arcs up or gets damaged, you can easily pull it off and replace it!! Here is my new little DRSSTC coil.


Here is were I blew one a while back...

Looks bad!!
The wrap does not "burn bad" so the actual damage was limited...
Just coated it with epoxy...
Brushed it up before the coating with a toothbrush,magnifier, and alcohol. Not bad at all!!
Here is the wrap from Office Depot...

...yes, my last two coils I've sprayed the PVC with Dolphs Lamination coating,..spray can. I dont bother coating the windings anymore. When the winding is done, I put a small amount of epoxy around the last few turns on each end, just to keep it from unwinding..........No racing spark problems, but, the aspect ratio has been a little higher with my last two coils,..4" by 23.5". I would think if your coil is that far off, its gonna arc through what ever coating you put on it, and, if you have a very heavey coat, it will make it that much harder for a possible repair,...but heck, I DONT KNOW !!!!
