What more to say? I wanted to suffer and wind my own pole pig (x-ray transformer really, but it turned out only being about 15kV since I needed more primary windings than expected). I really don’t have any idea how many secondary turns there were, at least 15,000 though. The core was scrapped from a dead x-ray transformer.
Ultimately it wasn’t very useful, it had an exceedingly high resistance on the winding which I think was one big issue, additionally the core saturated much sooner than I thought it would so I couldn’t get 110V in on the 40 turn primary. I think there was an arc inside somewhere too.
Winding jig… turns out Legos are still useful
A few layers in. Fortunately it’s only a volt or two per turn so small errors are not catastrophic as they are in a tesla coil
Finally… done… winding
Core and the windings in the bucket
Awaiting vacuum oil impregnation (don’t use 5 gallon metal buckets for this, they implode… oops)
After pumping, awaiting tests
