Homebrew Sideswiper - May 26, 2010.

UA3AO's homebrew sideswiper - May 26, 2010, click to enlarge picture. 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].
