Homebrew Sideswiper - May 26, 2010.
I made this sideswiper. Its parts were taken from a box of things to repair keys, bugs etc. Dimensions of the key's base are 100x70x4 mm. All yellow brass parts. Fingerpieces made of Perspex. Damper spring settings are made like the so called "swallow's tail" sideswiper. Such design resulted in a very good action. It is not a Stradivarius violin but a very nice sideswiper... HI. [UA3AO].

I tested it like a single keyer at QRQ up to 60 wpm. It works very good and has perfect operating feel. Base of the key made off gabbre ( sort of granite) and has dimensions 100x120x35mm. White metal is titanium. [UA3AO].
