Best way to punch IEC panel mount connector in boxes.

[Philbo King]

I cut them with a Dremel, once the hole for the connector's body is done I place it and mark the screw holes

Actually they're almost the easiest for me

I wish I had thought of this when I put an IEC jack on my Gates Level Devil when I restored it (it was a radio station dumpster find). That chassis has some serious iron on the chassis. It took me a couple hours to drill inside the outline and hand file it to fit.
