Matthias kicked my brain in gear and I went back and tried something else. A lot less complex than the last one. For those that don't know what this is, it will turn on my shop vac automatically when I start my miter saw.
VERY impressive work and I really like the idea! Any problem finding a rod machined accurately enough over that distance? A lot of the normal threaded rod I've seen loses or gains as much as 1/64" over as little as 12"
