Classic Torsion Bar Straight Key

11/4/2020 I’ve decided to put this key back in production. It now includes drilled and tapped rubber feet and the wire contact posts have been removed and the base now has an integrated 3.5mm jack. 

Wow! Absolutely beautiful, incredibly quiet and responsive action. Thank you!!!

What a finely made work of art.  It is absolutely beautiful!!!  I put it on the air hours after I received it and worked 3B9FR on Rodriquez island, RU3EG in Russia and several more. I am proud to display such a beautiful key in my shack!

Check out the great review by N1ABS!

It’s a whole new thing…no springs or magnets to mess with. Just plug it in, adjust the contact travel to your liking and experience one of the quietest and smoothest straight keys you’ll ever use.

The video shows my original design.

All components are made by hand. All brass parts are mounted to black granite and then mounted to an American Cherry base. The knob is hand turned out of Delrin and modeled after the Navy Flameproof key. The mother of pearl dot is no longer used in the most current model. Wood base measures 4″ x 6″.

A 30″ 3.5 mm stereo retractable cable is included

Each key will come with an engraved plate: “TBSK by W1SFR Ser No. XXX”.

Price: $365 which includes FREE USPS Priority Mail shipping.

  1. Steve,

    Our QSO this afternoon got me intrigued about your torsion bar SK so I ordered one! Looks like a fine piece of work and I will look forward to receiving it and getting it on the air!

    • Hi Justin, Thanks for taking the time to do the video. Like you say, there’s not much to adjust, but if something does get out of whack, it’s pretty easy to get it back into alignment. 73, Steve, W1SFR


  2. KB4DZN here – received my key yesterday – delighted! It’s a well-made that stays put on the desk. Got a dozen contacts so far and I’m adapting quickly. Thanks for a great key!!!!!
