I have yet to finish it since I ran outa money (too many hobbies, not enough funds,lol). I still have to get the acrylic sheet for the case (wanna be able to see it as it's powered in case there's an arc in the oil so I can shut it off b4 it's completely destroyed). Also need the pump for the heat exchanger. I also have yet to build the driver circuit for it, probably have to go the mosfet route since igbt's can't do 100kHz I don't think. Going on my experience from repotting an x-ray transformer (went from 1000+ lbs to 130), this is not something I want to actually start, stop for a few weeks or months and have it collect dust, then finish it and pot it in oil. I ended up having to repot the x-ray tranny twice because of dust and other particles (metal dust from dremaling excess metal bars and unneeded hardware that was welded on) got in the oil and weakened it.

Hi Mike.

Were you the one who posted a message
last month about building a pig style
transformer and using large ferrite's
as the basis for the core? If so how
did that all work out?
