What are the best resources that you have found for winding custom transformers?
prose, videos, forums, etc.
I am looking for things more on the practical side rather than resources explaining the basics of transformer winding ratios. Once I get enough responses, I will compile them into a list. I purposely did not differentiate between power and signal transformers, so I am hoping to get some of both.
For instance, here are a few of mine:

As from my experience:
You have to make a form (probably a wooden form) which is exactly the form of the transformer core, but longer.
For convenience make a winding rig - a place to attach the form connected with a handle and a shaft for wire spool. Wire spool has to have some kind of breaking mechanism attached to you get some tension on the wire.
Make a sheet of plywood with a hole exactly the shape of the form - you will use it slide the finished coil from the form.
Wrap a form with a thin cardboard, leave edges of the cardboard so that you can fold them and glue them together after you finish the winding.
The idea is that you attach a form to a handle, put a plywood sheet on it, then put cardboard, then wind the wire, fold cardboard around and use a plywood sheet to pull the coil off the form. Cover the form with soap or paraffin so the coil will slide off more easily.
This is all I have in terms of photos, please excuse the quality and incomprehension.
