This is last night’s test-fitting of our flatscreen to the mount I designed. It’s not hooked up yet (there’s a little more drilling and some cable routing left to be done) but it’s looking good.

What you can’t see here is the hole drilled through the bottom of the mount matched up to a hole in the floor so that power and signal cables can be routed down through the tube, under the floor, and over to the wall on the right side.

Next steps are to find a compact power cord I can run up through the tube, splicing a power outlet in the coal cellar below, waiting for delivery of a 35-foot HDMI cable, and installing a data drop in the wall behind the shelf on the right (out of frame). All the A/V equipment will live there so we’re not tripping over big black boxes in front of the couch.
