Shaft Extensions -- Done Right!

Postby brian » Tue Mar 10, 2009 3:45 am

The best sound results from shortest signal path. So let's keep volume, selector and signal wiring to/from inputs/outputs short and at the back of the chassis. That means shaft extensions are needed.
Have you ever tried them? They do the job BUT poor tactile quality. It makes even a good switch feel cheap. The problem is the way the shaft connects to the switch.

But the Uni-Flex Joint solves this:
The Uni-Flex is 23mm long x 18mm diameter. As it turns it adapts to the angle of the rotation axis and provides some mechanical decoupling from knob to switch. Even a cheap switch feels like a big $ one.

The shaft is 260mm long x 10mm diameter. You can cut it to length. Solid aluminum.

Also includes:
switch mounting bracket with adjustable height 10 - 50mm and positioner slot.
Brass collar for thinner faceplates.
