Hi friends
I dream about dream-machines all the time.
This time, it's about the pots. My dream goes like using two pots with one knob (for various reasons).
I am very pleased with the Precision Electronic's 2RV7, but they (the one I got) are rather hard to turn. Spec says "Operating torque: 1 oz/in to 6 oz/in"...
... do you know of a method to adjust it and make it smoother? (Besides using a bigger knob)

AFAIK this is done by grease with high viscosity on the shaft inside the bushing. There is other pots of same construction I played with. Disassemble and replace that grease with the regular one and it will start to turn easier. To be 100% certain that it is a grease not something else without disassembling pots first, try to heat bushing and shaft to 60-70C (or freeze it to -5-10C or both) and check how much easier/harder it rotating. if it highly temperature dependent then changing grease on the shaft definitely will help
Contact cleaner tends to wash out the grease, which means the pot will wear out faster than expected....
