Love this tape, I have some 30yd rolls of the 3M stuff. I think it would work fine, but it is a bit thick. You can streach it, but you will need significant overlap to get it to fuse without pulling apart. The steps formed from the edges may also provide issues.

Actually I already have two transformers here that I consider "successful"...although I admit I haven't tested then at full voltage/high power yet.
Right now I'm working on the multiplier, and as soon as I get that done, I'll work on a driver of some kind.
I continue to pursue other design ideas because I'm interested in these things and I'm just never quite satisfied...

@JP, I think if you could build a mechanism that actually winds the tape under vacuum you may achieve some worthwhile results.
Winding the tape, then placing under vacuum will surely just result in the air expanding within the windings, leading to deformation, and, maybe, breakdown of the insulation. While 'some' air 'may' escape, some will surely be trapped within bubbles within the coil.
While I admire your attempts at epoxy and silicon encapsulation, I can't help thinking that, maybe if you had applied your time and energy to using oil, you may have made more progress by now.
I agree that oil does have some drawbacks, not least expansion/contraction with regards to heat, and the possibility of leaks, your other attempts to date, especially regarding vacuum epoxy encapsulation, do, however, seem to be just as messy, if not more so, than using oil.
While I'm not suggesting that you give up on epoxy/silicon encapsulation, it does seem that all the methods you've tried so far have some unforseen drawbacks, and that maybe oil has some advantages after all.
@Xray, I had meant using oil 'instead' of silicon tape, not as well as. I do agree with your points, though.
