RE: [TCML] homemade transformer

How did you get the third leg out of the core of a three phase
transformer. Maybe you used one transformer from a three phase bank of
three single phase transformers. I really like those big square
cores...lots of work area room.

Hello folks.

It can certainly be done and there are several approaches to it. Finn
Hammers is probably the most professional and a beautyfull unit without
doubt. He build his one from scratch, I tried somethin a bit more
simple. I took a old transformer that was big enough and rewound it to
work as some sort of inductively ballasted transformer. Tough I built
mine without any special calculations and it certainly has some flaws,
it was well worth the effort. ( I had some help from Finn, which helped
a lot ) http://www.luebke-lands.de/tesla19.html
Lately I got a sturdy case made from welded plastics, but without the
nice looking window Finn used. Its good for something under 5KVa and was
in fact pretty cheap. Core was 8EU, wire 50EU and a weeks evening work,
even though I used hand winding and counting. I am pretty pleased with
the result, but ymmv of course.
