Drying day.

My original plan was to make the drawer today, but that plan didn’t take into account things like drying time on glues given the current low temperatures. Titebond PVA glue would be grand, but hide glue is something I’m still figuring out, so I’m giving it lots of margin for error. Especially as I found today that I almost had a major error during the glue-up; the use of a mallet to drive the top crossbar and back support into the mortice put torsion stress on the two end joints, as I knew it would (stupid mis-steam-bent upright) but I thought it’d be safe enough.

Nope. Small (1.5cm long) crack right there. Not critical; the wood is now stabilised by the glue and it’s holding well; but enough to give me a moment of thinking “wow, that nearly destroyed a week or so of work without the raw material available to do it over…”

I might just try to get a little glue in there and clamp it closed tomorrow, just to be safe.

Meanwhile, the rest of today went on getting the frame out of the shed onto the assembly table in the late afternoon, getting all the clamps off and holding my breath to see if the glue had cured (it had), and doing the last bits of trimming on drawbore pegs and the like. And then the last coat of shellac got touched on in a few places to cover some scratches and once that had dried (it dries fast outdoors), I moved it back into the shed as it was dark outside by now, and got the first coat of osmo going.

Just ragging on a thickish first coat here, in two parts (you can see the contrast here between the untreated side panel and the just-treated top panel). The plan was, on with the first ragging, leave for 30 minutes, rag off the excess and immediately on with another ragging, wait 30 more minutes, then rag off the excess again and leave to cure until tomorrow evening. Then tomorrow, I’ll take 400grit paper or wire wool to it, and rag on a thinner coat, leave for 30 minutes, then rag off the excess, then leave to dry until the next day, and we’ll do at least four coats of that.

In the meantime, I’ve a drawer to make up as well.

Also, this is WAY TOO BIG to be doing in this shed…

To-Do List (stuff in progress in blue:

  • Make a drawer
    • Thickness the boards for the drawer.
    • Cut the drawer front to size.
    • Cut the drawer back and sides to size.
    • Cut dovetails for drawer.
    • Groove drawer with #43 for plywood base.
    • Maybe add runners underneath the drawer?
    • Finish plane drawer front
    • Finish drawer front with shellac.
    • Paint drawer sides with milk paint.
    • Assemble drawer.
  • Last minute fettling and foostering.
  • Finish entire assembly with several coats of Osmo wood wax.
  • Close door of shed, lock it, walk away and never do another project with a deadline ever again.

Not done yet…

…but it’s getting closer.

I’m kindof cheating a little there – that’s a dry-fit before gluing in all the slats. But it all fits and the mattress top is at the right height so that’s a good start.

Got the day rolling by checking on the last coat of shellac for the rear support and especially the endgrain carving, which turned out well.

Then I put a tarp down on the assembly table, laid out the parts and rails, and dry-fit everything together. Then I stood the crib on the back panel, got out the hide glue and glued up the tenons going into the front panel, and then glued up the wedges and started driving them home to secure everything.

It went pretty well, even if one wedge did fail after I’d driven it home (it’s the one listing off to the left in the top photo). But enough went in to do the job, so it’s fine.

Then I took the flushcut saw and trimmed down the wedges, leaving a few mm proud only, flipped over the crib onto the front panel and inserted the end panel and dry-fit with the top panel and found – horror – a gap of nearly 2cm. The frame wouldn’t close. How I missed that I don’t know, but I spent the next hour fettling the top panel with jack and smoother and shoulder planes to get it to fit properly.

(Got to sign the work)

Then once I had it fitting properly…

I painted the tenons going into the back panel with hide glue, seated them, painted the wedges with glue and drove them home as well.

Then I got some (now in bloody awful shape, I need to fix these again) of the heavy-duty clamps I used for the bench and clamped front to back panel to get good pressure on the joints.

And then there was some tea. Then I dry-fitted the back support and top crossrail and the slats.

There had to be some more fettling of the back of the mattress support platform (and will have to be some more still, I’ll do that tomorrow), but it all seemed to fit fairly well, so I stuck on the mattress to make sure that it was 510mm from ground to mattress top.

Yup, all good. And the grain pattern on the rails matched better than I’d hoped it would. I did have to remake one slat from a spare I had, but by the time the light was fading, I had the curved uprights glued and drawbored into the top crossrail and that glued into the main body and all the slats glued in place and clamped.

The question now is whether the hide glue can hold the slats on the left into the frame, as that curved upright wants to spring up and away from them. If it doesn’t hold, I’ll swap out the hide glue for titebond; but it should be okay.

And that was all there was for the main frame. I still have to fettle the mattress platform a little, that’s a five to ten minute job, but we’re just about done and onto finishing with the frame.

And all that leaves….

…is the drawer.
