Thanks Russ,
Parts box here is not quite the option it might be at your shop
Your other concerns are certainly good ones.
The type of pot on which I was going to attempt repair is the '30s design with no sliding contact directly on the track - a strip of sprung steel matching the track is pressed from behind by the wiper. Presumably this was to avoid/reduce wear of the then fragile track print.
As to accuracy of the curve, perhaps this is not so important, especially for audio use. Mostly I am interested to see what can be done, purely out of curiosity. My "radio time" is purely recreational, so wasting time on this is fun. First thing I'll do is try a test setup - an easy 1/2 hour experiment on some scrap materials.
Cheers,
Ed

I don't hold with furniture that talks.
