I was considering building my own toroidal transformers using 20awg soft steel wire for the core.
I want to wrap the wire into a coil of the width and thickness I need and
then wrap the copper wire around that to produce the transformer.
I need a fairly large toroid of a certain size and dimension.
Any advise on how to go about doing this.
I already have the soft steel wire, I tried running a strong magnet over it
and proved it doesn't stay magnetized, so it should work for the core.
I know this is a pretty crude way to make a transformer but it's the cheapest
way to get the size I need.
I'm not sure of the exact dimensions I need yet thus the reason for
making my own cores; so I can test various sizes without spending a fortune.
So any advice would be greatly appreciated.
