The rafter in question is only a problem because it runs down from the attic and through where a wall needs to be. The wall needs to be built around the rafter. If it was straight, it wouldn't be a big deal, but it isn't. After a couple of mis-guided attempts and a few new skills, the problem is solved. Or at least it will be once the walls are up and no one can see it what I've done.
In other news, our windows have arrived, we'll soon be installing them. I have a feeling that this great weather will run for the hills the minute we go to put them in.
