Sticking a finger into a spinning planer blade has somewhat slowed things, but I have managed to make a couple of upstairs doors in the last little while. Here is the story of one of them, but they're all fundamentally the same. You won't get this repeated for each of the 4 upstairs doors I am doing in this batch.
You might recall I made ledged and boarded oak doors with hand-cut cinched nails for downstairs, 5 or more years ago. Upstairs rooms have had 1970s doors temporarily fitted in the opening for goodness knows how long, so I am just copying the doors from downstairs (a mediaeval design). The process is fairly quick, except for shaping the middle board. It started with ripping the sapwood off, and then paying a visit to a friend who has a big planer thicknesser, capable of handling these boards which are up to 375mm wide. That was the rough grunt work done. I then finish planed the outer two boards, and turned to the middle board. I started work on this with an electric plane to hack away the bulk, then reverted to a scrub plane:
After putting a rebate on the inside edges of the outer boards, you end up with a section looking like this:
After cleaning up the edges, and chamfering on the exposed edges, it's time to assemble. My little hidden secret is to insert metal dowels into the edges of the boards, to prevent one board dropping in relation to another. I've used 5mm brass for these:
My other little secret is to countersink the holes which relate to the edges which I'm allowing to move with seasonal fluctuations of humidity levels, and gluing the ledges on at the point of the boards which I want to hold in place:
So you can see that the outer dimensions of the door won't vary, and if there is any movement it will occur in a gap I have left between the boards (although both the new oak for these doors and all timber indoors measure 5 to 6% on my moisture meter, so there shouldn't be a lot of movement). The nails are thin enough that they'll flex in the gap formed by the face-to-face countersinks:
They're French machine-made traditional nails, and the factory they come from is an incredible time-warp.
One little subtlety that you'll only ever think of if you build doors like this, is that at least some of the nails for each ledge are unavoidably nailed up from the underside, which is a pain in the neck. Once they hammered through (a G clamp helps hold everything together whilst hammering..........F clamps come undone), the nails (46 per door) are folded over:
The ledges are shaped all around to try to avoid a square-edged look:
After doing a final sizing (yeah, righto) using a soft-melt glued pattern taken from the opening, it's time to screw on the ironmongery:
Hanging the doors is relatively straightforward, as the pattern-taking ensured that they were all-but spot on straight from the workshop. The "smart" side traditionally goes to the hall/ landing, and the ledges face into the room:
Door stops will be done in a batch when all the doors are hung.
