[Amps] 1/2" bore Control Knob

[Harold B. Mandel]

Dear Chris,

Do you have access to a metalworking lathe and a drill press?

Use a two-inch diameter piece of Lucite rod, drill a 1/2" hole
about halfway through on one end.

Drill a #36 hole on one edge through to the 1/2" bore.

Drill a #25 hole just about halfway down.

Tap with a 6/32 thread, run a 6/32 set screw in.

15 minutes and you got a knob.
