Making parts:

I wish the ARRL would put out a book on how to make capacitors and re-winding transformers, etc. Some parts are impossible to find at reasonable cost. It is too bad to dispose of gear that can be repaired. I have re-wound an Atwater-Kent radio power AC transformer early in my ham radio career. I would have liked to know how to do that right the first time. I know faulty capacitors can ruin transformers. Older gear should be more repairable than solid-state parts that are no longer made for one reason or the other. I would think one could make vacuum tubes if one knew how to go about it.

A quick search of the QST archives produced a good article on rewinding transformers.. And, I think the subject is covered in some older ARRL Hanbooks.

What type of capacitor do you want to build?

Most of the parts that one could build probably wouldn't require an entire book to build, but I'd love to see a few newer articles on the subject.

I used the Periodicals index and tried the following searches:

winding transformers
construction homebrew capacitor

There was at least one article on building a variable capacitor, but you'll have to scroll down a bit.

Homebrewing some components would be a real challenge. In a variable capacitor, very minor vibration would translate to a change in capacitance, which would make for a very shaky variable-frequency oscillator, for example.

You may also try Lindsay books. Lindsay often has "old technology" books like the one you wish for. They are on the web, I forgot the address, but they offer reprints of books from "way back". Many are about making old style radio parts-- including vacuum tubes!
