RE: [TCML] homemade transformer

I have removed secondary windings from standard "E-I" cores where the
secondary was on the outside and made high current filament transformers but
that showed me I was a long way off in skill and winding equipment to make a
high voltage transformer. It was just 5v@30amps. The  cost of a custom made
core is more than I can afford for a hobby today.

Hey Clive,

I tried it once.  Once was enough to show me that what I thought was 
going to be an easy thing to do was an expensive lesson in that I didnt 
know poop about transformers.
A few things to consider even before you buy/obtain materials...
Core Material, Cores size, ampreage rating in and out, voltage rating in 
and out, insulating properties, wire size both primary and secondary, 
hysteresis, eddy currents, flux fields, gauss lines, Teslas( magnetic 
strength) and your ability to do upper level math :)

its not that easy, thats why Electical Engineers design these things.
plus its easier and quicker to buy a piggie or NST or salvage MOTS

but if you have the time, resources and patience to take on a project of 
this type Im sure we would all like to hear from you and the progrees 
you make in your endevors.
