Hi,

https://wiki.microwavers.org.uk/G3WDG_Microwave_Designs    >

has the complete description.
You should try if you get by with pipe end caps. The tuning range is huge
and you can see what you get without soldering the cap. Slight pressure
is enough.

Last summer, I have made some measurements, too.
But my VNA works only to 8 GHz.
