I got a bit of enabling work done today. I wanted to lay the base beam for what will become a closet, but there was a bit of floor missing. I can't just replace it because the bits of floor that were there were unsupported - a section had been cut away so the old bath could be connected to the pipework under the floor.
So the first thing I needed to do was cut everything back as flush to the joists as I could manage, which was tricky because the base beam for the new wall was already there. But I managed to botch something with my jigsaw that just about had enough reach, as long as I moved very slowly. The last bits fell prey to my oscillating tool. Then I could screw some wood to the joists to support the ends of the new floor, fix a nasty cut someone had made in a floor joist somewhere along the lines, and get a small piece of floorboard cut to length and put in place.
It seemed like a lot of work to achieve nothing more than being able to fit about 30" of base beam but it beats leaving things inadequately supported. Some of it might have been overkill but given how cheap a lot of stuff is I'd rather spend a dollar on structural grade screws than save a few cents and find something sags way down the line.
So tomorrow's job is going to be to frame a bit more of the closet. The final part of the closet will overhang where a piece of the new flooring needs to go, and I need to decide what color I want that to be stained, so that probably won't get finished off tomorrow. But maybe I can fit a floorboard, frame the wall over the top of it, and stain the bit that's visible. I'm still trying to figure out the best way to stain the floorboards and wipe off the surplus without staining too much of myself in the process. It could be tricky. Maybe I need to find a really ancient pair of socks that are disposable, so I can just wear those and throw them straight in the trash when I'm done with it.
