DIY String Pots

I am aiming to overcome my natural ineptitude and build an oversize midi controller.

I am most likely going to use a 10 turn pot with a pulley attached to the shaft. I am thinking I will also need some kind of bearing to support the shaft of the pot and protect it from the sideways force of the belt/ pulley arrangement.

Can anyone point me towards finding pulleys and bearings that will fit on potentiometer shafts?

I realize this is probably a riduculous question if you are in the know but I'm Googling round in circles (rs, cpc etc).

Thanks,

Gavin

PS I was hoping to use String Pots but they seem to cost over =A3100 each. I only need a low res device. Are there any other alternatives?

McMaster-Carr has a broad selection of pulleys and bearings, but based = on the 10 turn pots that I know, you are going to have some work = adapting something to the pot shaft... definitly feasable though... just = a bit of a job :) Something along the lines of some angle and flat = aluminum arranged line THIS:

|| || [pully]=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D[pot shaft adapter] || || =3D=3D=3D=3D=3D=3D=3D=3D=3D = =3D=3D=3D=3D=3D=3D=3D=3D=3D = =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

1.5" angle stock, with a piece of 1.5" flat as a baseplate... use 1/4" = ID bearings with 3/4" OD flanged.. use 1/4-20 threaded rod for your = shaft, and the pully of your choice with a 1/4" shaft
