Hello.
How can I make a 0-600 pF variable capacitor, in an easy but elegant way?
Thank you all.

Hello.
Building elegant variable capacitors is an art. Building a working variable capacitor is very easy, but building it elegantly is difficult. You need to know how to work iron and mechanics well. Anyway you can see some videos on youtube, but I haven't found a really professional video yet.
Greetings

Very old "valve"/"tube"radio sets (up to about the 1960's!) often used large multi-vane air-spaced variable capacitors of up to 0-400pf, and maybe higher - possibly in sets designed to work at very low frequencies, especially those for military use - and so I'd have a look for designs for those and see if you can identify and then obtain a suitable capacitor.
