Using one of those former to build a transformer from scrap

Ok you make a former and put some wire on it then what? Find some strip material. Banding is good. Next time your at the lumber yard and the guy cuts the bands from a bundle of lumber ask if you can have it. Then cut it in strips to fit your core.

That's half maybe three quarters of the job. It will function but not as efficiently as you would like. It needs some closure around it.
 The squares will surround the coil and the 'U' bracket will be the mount.
After installing the squares I pushed the 'U' bracket through the core. All that is left is to bend the brackets outward.

Here it is installed on my amp board. I made three. Two interstage and one output transformer.
