, simple hack for those who don’t have a handy drill press. Clamp two plates together, drill a couple of holes outside your usage area, apply bolts. Or pins. This keeps it from shifting at all.
Then all you have to do is make sure your drill is vertical!
Of course, a drill press is handier. So is a cnc machine. Or, and this is what I will probably do, 3d printing them. If my new printer ever arrives (it’s stuck in customs, seems they don’t like my address. I’m rural, not everyone is in the usps database!), I will be doing it that way. Hence the CAD files.
