winding yer own transformers, somewhat OT.

[cyborg0 at GlobalEyes.net]

ok, well, since all this transformer talk has been going on, I have a question..
I havent wound my own transformer since Physics class, and, as we all know, the
classroom is kind of a controlled enviroment..

Ok, I have been dabbling with winding hi voltage transformers for projects like
jacobs ladders and such and usually i do it exactly the way it is the the books
and it works, but this time...

 I recently bought a pre-made ferrite E-core complete with a hollow spindle and
clips..nifty... I thought I would treat myself instead of going through all the bs
of riveting a bunch of sheet steel Es and Is together to make my own cores.

Ok, now, the only problem is that the spindle (the middle part of the E) where you
wrap your wire is about twice as long as the one in the plans. Obviously, this
will make me be able to get more turns per layer..

Now, I know the number of turns is critical to the tranformers behavior, but, is
the number of layers critical also?
Anyone have any answers? Maybe some of you power supply ppl?

Oh, btw, this is somewhat on topic because it would be neat to be able to wind
your own audio transformers and go from line level to balanced, so it has some
applications in syths..you could experiment with different turn ratios..
Although my turn ratio is about 1:300... :)
makin big voltage..
