I moved the chassis I bought into the makerspace for use. NOTE: they should have a bag of anodized #4 screws somewhere with them. They have holes for these screws, but I found that they need to be tapped for the screws to work well. The anodization is too hard and thick for the screws to self-tap.
Please machine these as needed to mount electronics within.
I haven't moved them yet, but we also have D9 and D25 dsub hole punches. We are getting a BNC 0.5" D-shape punch, but it has a long lead. For now, just drill 0.5" holes and tighten washer if you need to add BNCs to front panels.
