How to rewind a variocoupler?

[jbivy]

I picked up a pretty trashed homebrew receiver at a pawn shop. I was able to salvage two large bakelite variocouplers, three of the five bakelite tube sockets and the binding posts. The knobs have puppy chew marks on them and while cute, theyre now junk, but not bad for 30 bucks.

Does anyone know where i can find a tutorial on how to properly rewind these variocouplers?

Theres a few designs ive seen that i would like to try out, but they call for variocouplers. I assume i use the length of wire as called for in the right gauge and just wrap each part?
