I have actually, at least a little. We had some 2x4 studs left over from farming mom & dad's house, so I framed up the office area (just realized the pics I posted were the same as the ones I did earlier, so will delete and put up new ones soon.)
I put in a MrCool 36k btu minisplit in the corner of the main area, and a second 18k btu minisplit with two 9k heads, one to th office and one to the welding grinding area. These seem to do a good job keeping it at ~ 80 degrees (I could keep it cooler easily, but why spend the $$$$ when I'm not even out there) Mr Cool minisplits are an easy self-install if anyone is interested. I got an electrician to help with the breaker wiring of the first one, but didn't bother with the second one - very easy to do.
I also have hung the rafters over the office, and I've run some 20 amp outlet circuits.
Once the stuff I'm storing for Mom and Dad is out, I can put in the lights. I'm planning on UFO style Hi-bay LED lights. Getting conflicting info on how many and power. The ceiling is ~ 14 ft at the edges and ~ 18ft at the center. Leaning toward 100W 14,000 lumen units or 150w 20,000 lumen units. Any thoughts on this?
With any luck, mom and dad will be able to move into their new house by the end of October. (And get their stuff out of my shop!)
