This is the view inside of the ceiling with the new wire pulled in through the hole in the laminated beam.

The patched hole in the wall. This requires another coat of joint compound, some sanding and then paint to give it the finished look

This hole was made using "The Grabowski Method" of cutting holes in drywall. You simply hold your compass saw at a forty five degree angle when cutting to give you a beveled edge. This makes it much easier to patch the hole using the same piece of cut out drywall and some joint compound.
The completed wiring job for an additional dimmer and a new light fixture. All that remains is to have the holes finished and painted.
