Hello,

Attempt number two on the toroid went better.  Still rather homely, but 
everything is relative.

I have another question for you guys:  Over the weekend I wound a secondary 
out of #32 heavy build, 13" of windings, on 2" PVC pipe.  I want to keep 
this small, so I plan to mount the whole pri/sec assembly on one of these 
12" fiberboard circles that Home Depot sells for about two bucks.  The 
toroid is the previously mentioned disaster with measurements about 9 by 3 
1/2.  I've collected a wide variety of transformers over time, and was 
hoping to use a 5kv/20ma ignition transformer that I robbed out of a small 
space heater.  Would this be acceptable, or would I be better off with one 
of the 7.5/30s?  I have looked thru the archives and tried to search the 
Tesla Ring (hard to find anything using keywords on the Webring), and 
haven't come up with anything definitive.  This is my first coil since I 
was a kid (Model T coil driven; didn't work so well), and I would like to 
avoid screwing it up right off.  Looking for a few thoughts given the 
secondary size.

Thanks,
John Richardson
