Default Re: Improvising with Household Items.

I once made up some replacement bias- and filament-voltage-potentiometer knobs for a restored no-name 1920s 3-valve radio by using hexagonal nuts from old 3/4-inch brass compression-fittings. A modelmaker acquaintance turned up some brass bungs to fit inside the nuts, with a 1/4-inch hole bored down the middle for the spindle. Nuts were then soldered to the bungs and the final result looked rather chunkily appropriate given the overall design style of the radio.

Old radiator-valves also provide inch-and-a-half lengths of 1/4-inch-diameter brass rod, and the gland-nuts can be repurposed/cleaned up to serve as nice brass bushings where you want to extend or support a control-spindle.
