This is the corner post of the oak screen I made a couple of years ago, and I am about to plant another post alongside it. I thought I would leave a warning for anyone who didn't like my work:
Some of these pictures get a bit complex. Here is a photo of the southern bridging joist projecting into the stairwell. Not only does this need cutting off, but it also needs supporting. At the moment, it is hanging from a pair of timbers on the floor above. The timber I am talking about is horizontal, in the middle of the photo, and has a little black still showing:
You can see it half way up the right hand side of this photo:
I waited until my wife was out of the house for a couple of hours, and with every window in the house open I used that well known piece of delicate woodworking machinery, the chainsaw:
The fumes were awful! Next, I had to carve a joint in the end of the old bridging joist to match this one in the beam which will support it:
This joint won't be visible, but it will need to be strong. I roughed away the worst with the chainsaw:
Access wasn't easy, but it turned out well, and I cleaned it up with a chisel. Lifting the beam which will support it into place was simple, as it was alongside studwork enabling lots of opportunity to clamp in supports, and then once at the top, the beam could just rest on the top of the studwork until it was slid into position. Now, remember that this beam is between two post, with a tenon on each end. That meant leaning the big post i put in the day before out of the way. With nothing to rest it against, I had to improvise:
Note the top of the beam about a foot out of line with the lintel above it. Towards the bottom of the photo you can see the studwork which temporarily held the new beam. Back to the other end of the new beam:
It is impossibly to see the joint with the old bridging joist, but that went in well. Remember that these joints are impossible to try beforehand, so I had made careful template to check that everything fitted. This one went like a dream:
Both ends were perfect! I have worried about this piece of structure more than anything else in the last year or more. The right hand end of that beam will be the first thing you see as you walk in the front door of the house. The left hand end you'll pass every time you use the stairs. Cocking either of them up would have haunted this build forever. This is one of those things I have woken up in the middle of the night worrying about. I really wouldn't have been more thrilled if I had hit a century in a Test match at Lord's.
I quickly fixed the studwork into place, and plasterboarded it. The downstairs loo now has a wall again!
The next big lift was the sister of the 2 storey vertical post I put in the other day. It was another 2 man job, and it went well:
Note this view:
This is from the kitchen through into the lounge. Both of these room are to get a structural door frame, and then across the gap between the heads will be a beam forming the head of the stairwell, and taking the long side-piece. The post on which I wrote the message in the first photo is on the left, nearest the camera.
Again, there is a tenon on both ends of the beam, so the newly-positioned post had to be leant out of the way to enable it to fit between:
The left hand post has the light switch in it, so there is a rebate house out of the back for the cables. This photo was for my benefit, not yours, so that i could be sure of getting the wiring right (this is the temporary surface mounted switch we've used for a year or two:
Note that the two posts are not loadbearing. Structurally, they hang from the peg holding the joints together. There is no foundation under them, and there is insulation under the screed. The head of the door will be holding the weight of much of the floor around the stairwell, plus the weight of the stairs.
I wish I'd got a photo of this joint going together. It is a haunched mortise & tenon, for a really good load-bearing junction:
You can just about see the mortise on the RH side of this photo, right in the top corner:
Moving across to the lounge doorfame. One end of it gets its support from the brickwok of the fireplace. I couldn't use an angle grinder because it would have filled the entire house with dust:
The lower photo shows the post propped roughly in position. Note the small cut-out at the top for wiring, which again will be channeled down a big rebate in the back of the post.
Here is the completed doorway:
Right, that leaves us with just two principle timbers to complete the stairwell structure. This mortise was made and positioned a year or more ago:
Here's its partner, for the other end of the stairwell, in the beam which will bridge across the two heads of the doorways I've just put in:
Here is that beam in preparation, mainly just to give an overview of my "workshop" in the dining room:
I thought I would show the ends of the beam, rather than hide them behind plaster:
And this is where I reckon it will end up:
That's looking up at the kitchen ceiling, with the door-head to the left of the photo.
