Re-manufacturing Carbon Resistance Strips in Slide Pot

[David Forsyth]

I have a need to rebuild some slide pots from 1970's musical equipment that
have worn-through resistance strips. The pots are long since unobtainable
(made by CTS), and I have yet to find any suitable replacements. The
resistance strips inside the pots are removable, and consist of a die-cut
non-conductive substrate onto which a carbon resistance compound was bound
and on which the slide contact of the pot slides. Each end of the strip has
a metal connnector crimped to it to serve as an end terminal for the pot.

I think if I knew what kind of binder and process is commonly used to adhere
the carbon to the substrate I could restore the resistance layer. It would
most likely have to be baked onto the strip, which is not a problem. For
the resistance material itself, I was thinking of using material from carbon
comp resistors (it would be trial and error to find the right value for this
application). So, I am trying to find information on how resistance
material is bound to a substrate for use in wiper/pot applications (it would
have to be fairly resistant to abrasion, solvents, etc.) Please email
foda01 at epix dot net with any helpful info.

thanks,

Dave
