Mike, you cap looks a lot like mine only your using thinner polyethylene!

I remember an article in a back issue of Popular Electronics that was on
building HV caps for TC's it used PVC pipe for the tank
looked like a good design, I'll see if I can find the issue.

Hay, don't we all!! Besides even if we could afford to just buy
everything there would be no fun and no learning!
