I agree with Steve, Manfred's treatise on transformer construction is first class. Loaded with very practical advice and it demonstrates that he has much experience in making transformers. I only made one in my life, 
in college at Virginia Polytechnic, as part of a lab course, we had to make a small power transformer. Most of the guys (there were no girls in that class!) couldn't get their winding on a bobbin without it falling off the edges,
and for some reason I decided that a piece of tape across each layer, plus putting glue (not varnish) in the ends to seal it tight would make it stay together. Some patience needed also. Mine did work, transformation correct, and I may have  gotten 
an A grade in that lab, but that's as far as my transformer design experience went. But Manfred's website makes it look fun and - well, not exactly easy - explains the sorts of tricks are needed to make a tight, compact,
reliable and functional power transformer. Thanks for putting that together and in the public domain.
