Can some mechanical engineer tell me why this stupid thing is keyed like that?

Because that means I can’t just drill a hole using a regular old hand drill and jig, or even a drill press. I reckon there’s some kind of slick metal-shop dealio that does it, but damn, it kinda hoses the old “let’s fool around in the garage and build something with this” ethos. I guess I could grind it off, huh? Or get the ChiComms to make me one without it.

PS I’m studiously ignoring the enormous pile of invoices and POs on my desk, and QuickBooks lurking down on the menu bar. Man, I hate accounting. “Balance sheet? Whaddat? We got a balance…not much, but it be a balance.” I just want to make stuff and sell it. I can’t wait to hire an office manager. Sigh. OK, then, let’s get to it. I’ll treat myself to a paddle later.
