vacuum variable capacitor 3d models

This fits the drive shaft of a vacuum variable capacitor that I have. Shaft is ~12.6 mm in diameter (the bore in this part is 12.75 mm). Shaft also has a crossbar thingie going through it which is 3 mm in diameter and perpendicular to the shaft,...

A model of a 10 kV, 0 - 300 pF vacuum variable capacitor that I have. It's stamped with C.M.C-147-684, which may be a model number. No other markings apart from voltage rating. It was listed as a Jennings cap on eBay, I think. This is not a...

Variable capacitor

variable capacitor for old school radio design

This is a variable capacitor, by turning the vertical axle you can change how much the plates overlap, changing the capacitance of the device.

Old school looking (ish) variable capacitor. ...My super ultra cheap Part Tester/LCR meter (probably not at all accurate) gives me a capacitance range of about 25pf to 130pf.

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically.Dear Guest! If you download this model, hit "like". ...Enjoy :-)I will also be grateful if you give me an idea of a new project you need.

A mostly-printed variable capacitor. I don't necessarily recommend making this one, as I designed it around what I had, and it isn't perfect. This is more sharing for inspirational purposes :) Uses two 100mmx70mm single-sided copper clad...

This is a 3D printed butterfly type variable capacitor. Can be extended to any length/capacity by just adding more plates. Distance between rotor and stator plates is ~ 2.5mm. Currently contain only 3 plates for the rotor and 4 sets for the stator.

I found a need to extend the shaft of those cheap Chinese variable capacitors to make them more useful in my radio projects. So, here it is. You can extend the shaft to your own desired length. It is a good fit on my bag of VCs from China and has a...

Haven't installed the plates themselves for testing of the capacitance yet.*** A variable capacitor designed to be approximately 10-120pF. I have not printed this yet, so it's all mathematical at this point. It is designed to use two 40mmx80mm pieces...

It should fit most of those little plastic variable capacitors. All the ones I've found had the same shaft size and shape. You'll need some short 2.5mm bolts for the capacitor. If they're too long they'll short out the capacitor. The knob was...

... of the bolt. I made a bottom mount, and a panel mount version. Both have 4mm bolt holes. My variable capacitors use 2.5mm bolts, yours may be different. I will likely make a version for air variable capacitors soon, as I have some in the mail.

Insîred from https://www.thingiverse.com/thing:2252121 The bracket was designed to clamp a KP1-4 5-100pF 25kV variable vacuum capacitor together with the 28mm diameter ends of the copper tube from the magnetic loop antenna. The contacts of the...
