[Hallicrafters] Main Tuning Knob - SX-101/101A

[Roger Halstead (K8RI)]

It would be my guess, and I emphasize the word guess, that to go without the
brass insert that is going to have to be some tough plastic, or possibly the
shafts will require "flats" be filed on them to prevent slipping without
having to torque down the screws.
