Re: Stiff pots
Spray some WD40 in a used bottle cap or something (spraying it directly on there will make a mess), then dip a toothpick in there, then put the 1 drop on the pot shaft and turn it back and forth so it get's in there where the shaft and the outer threaded part meet, it will work! (do the above with contact cleaner first to clean off any surface corrosion first, then the WD40).
......Man, that spins smooth! VEEERRRRRYYYYY NIIIIIICCCCEEEE!
