Hello LFers,

How critical is the spacing between the windings and the core material when
winding a toroidal transformer?  I have a core taken from a television
flyback
transformer that I'd like to experiment with using different winding
techniques.
To simplify things, I was thinking of putting the windings onto bobbins that
could quickly be slipped on and off of the core.  Would I be OK with using
a bobbin with 1/8 inch (3 mm) wall thickness or should I look for something
with a thinner wall?  Any and all comments welcome.
