[Amps] Home-brew ceramic insulators?

[M1AQV]

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!
