i cut the transformer cover along the top left and right sides  in three cuts then pushed the metal inward making a vent to let heat out.

i could have drilled a nice pattern of holes on either side as well.

my xfrmr wiring was solid and no breaks but..... the diagrams called out colors and my cotton braiding showed no signs the cotton was ever a different color than brown.  i slipped color coded heat shrink around mine.  your prob better off using an old junk yard auto wiring harness to obtain wire,, all 105degC or more rated and made for putting up with heat.  you will end up with a lifetime supply of wire.

i give these away as christmas gifts ... an example of an easy storage means to lots of wire.
all the wire is spiral dropped into the can and you pull out the amount you want.  i have a much larger can i use , one person i know uses a big old cheese ball container,, you see them at the store sometimes , they are about 2ft tall with a big lid.
