Got all of the switches and rotary controls mounted. Actually turned out pretty good. Used Dremel to make pilot hole, then regular drill to enlarge hole.
I had purchased new pushbutton switches because I thought I didn’t have enough already. After I had mounted the new ones, I got the old ones to finish out the panel.
Wow – see the difference? The old ones are made much better and have a true red pushbutton. Back to the parts bin and I was lucky to find enough of the old one to complete the panel.
Made a final fit check and drilled the holes to mount the switch/rotary panels.
