Short Shaft Control Knob

Radio Knob for
            Tuning Capacitor with Short Shaft

This type was chosen because the grub screw fixing is quite low down on the shaft and there is a recess in the black plastic on the underside.  This allows the tuning knob to fix onto the fairly short shaft of the variable capacitor, and the recess in the plastic avoids them clashing with the variable capacitor fixing bolts.
