Just drill and tap.
I could but I'd like finer threads than 12-32. But my boreing bar for tapping needs a minimum sized hole, at least 10mm. And no brass screws of that size on hand in Lewis County anyway. Steel would rust and plug things up. So I've changed my mind, I think I'll make a hose crusher, nothing to corrode that way. and I can do that in an hour or less with 2 3mm.7 screws and a piece of 1/8" alu panel. I've rx'd some din rails, so I can fasten down some of the relays I've used so far yet this afternoon as soon as I find a round tuit. Got the missus fed and coffee'd so I can dissappear for 2-3 hours. The guy in hongkong is going to ship the switches again so maybe I'll eventutally have some home switches. He's starving though, 100 miniature, 4mm sq, 2.5 mm thick waterproof pushbuttons for 2.42 USD with free ship, couldn't pass it up. I used a similar switch for X home on TLM, only knocked it loose once in about 5 years when chips got piled up in front of it. Should work ok on this thing.
