Here's the new-and-improved version of that window header. I'll probably eventually put in a door, but for now, I just put back the crappy window that was there.
As for the big 4x10 header I put in over the entryway... I noticed a fairly significant knot that's not looking too good, and seems to be in just the wrong spot. It's a lot worse than I've previously seen in "select structural" grade lumber. That's kind of annoying. Anyways, I decided to replace the beam with a Parallam beam. I'm hoping to have everything done by tomorrow and I'll post some pictures.
