Not nearly as exciting of a home mod, but finally bit the bullet and cut a hole in my vaulted ceiling. Was always a bit wary of doing that, since it's nearly impossible to access that area in the attic. So screwing it up, would be a real pain in the ass to patch up.
I got pretty fortunate, there was a break in the insulation at that point, so I took a rake and a couple of PVC pipes and could push them to the sides so I could barely see the hole in the drywall. Propped up a PVC pipe for a little assistance. Figure get the end of the conduit onto that, then I could guide it in place from the living room.
Not pictured, I cut up some plastic to make a flange that wrapped around the inner coil, to catch on the drywall and hold it at a desired depth. One side was to wedge against the joist where the TV mount is, so I could spin the conduit to adjust the amount exposed. But while I was messing with it to get it in place, I must have screwed up the flange piece, cuz the conduit came down too far. Gave it a twist, and it bound up.
You can't see it from the couch, but when you come in the front door...
I'll try to tap on it with a hammer after I get the cables pulled, and the cap in place. If I can't get it close to flush like I planned, I'll try a PVC cap, or something.
I got a spool of speaker wire, so I'll need to extend my front speaker wires to reach the new route. Once I get those done, and pulled up into the attic, I'll zip tie them with the other cables already up there and pull the whole bundle down in 1 shot. The rear speakers will get run through the attic and dropped down into the back wall at a later time.
Was smart enough to pop allergy and pain pills beforehand, so I was in good shape once I got that done. Decided to get some yard work done, cleaned up some leaves. Ran some errands, and that's about as productive as I'm gonna be today.
