Repairing a Hallicrafters SX-111 Knob

 There was a piece broken out of the edge of the knob. Considering the age of this radio from the early 60's, I decided to try to repair it.
 
I made a little form to follow along the inner curve of the knob with tape. A small bit of 5-minute epoxy was built up in this area and allowed to harden over night.
 
I removed the tape, and sanded the outer curve and edge of the knob to match. Using a Dremel tool with a cut-off disc and a jewelers file, I replicated the grooves in the outer surface. After cleaning, it's now ready for a little touch up color to match, once I get that mixed.
