On a similar theme, I have an old Heathkit ATU which has broken
porcelain insulators on the variable caps. I wonder if I can glue the
parts together? What type of glue should I use? Failing that is there
another material I could easily make replacements with? I plan to use
this ATU with my Drake L7 so it would need to withstand that kind of
power. Any thoughts/recommendations greatly appreciated!

• I bought 50-lbs of porcelain clay and I tried making porcelain
pottery. The shrinkage factor is about double ordinary stoneware clay,
and porcelain clay is hellish to work with. My advice is use G-10
fiberglass-epoxy for insulating. It's good around RF, strong, and easily
drilled/machined.
My YL has a ceramics business, and I started thinking about trying to
manufacture my own ceramic (porcelain) insulators. Has anyone tried this?
