Daybed: Shaping the Platform

All of that fussing around with making those clamps has finally gotten me ready to get started in earnest on my next project: a daybed/”couch”-like thing for an area of the house that currently has zero furniture. I had a sort of “vision” about how I wanted it to appear one day, and knew that I had to build it before someone else in the house bought one, because what I imagined seemed pretty neat, at least at the time. And when I read what Roubo had to say about them (yes, it’s in there), I became more convinced.

I wanted this to go a lot more quickly, but getting the large platform glued up took much longer than I had wanted–I had to make a whole bunch of stuff, including the clamps, before I could get to where I am now.

The first operation on the glued-up platform (after planing it off) was to shape it. I started with the ends, which are to be semicircular. I don’t have any trammel points to make a beam compass for such a large radius, so I just drove a couple of small nails into a board at the appropriate distance and used that to scribe it out:

As made, the radius of this improvised beam compass was a little too much, but to correct it, I just tapped one of the nails to bend it inward. I marked over the scribe line with a pencil.

Then there was a curve to lay out on the front. I guess I’ve been watching too much “Tally Ho,” because I tried to imitate Leo’s curve marking with a batten tacked into place:

I wasn’t sure if this would work, but it did. There were a few options for curve shape, mostly dealing with the tangent angle at the point of inflection in the middle. I chose a fairly mild one.

So I had one side done, and to do the other, I traced that side’s lines onto some of the paper that I use for making patterns, then cut along the lines on the paper, flipped it over, and transferred the lines to the other side of the platform.

Then it was time to start removing wood. I always get a little nervous the first time I cut into a panel (especially one that I’ve spent so much effort on gluing up), but it had to be done:

I removed as much as I could with a saw, working my way around the ends and trying to get as close as possible to the line. The cuts on the long grain were more challenging, so I used a drawknife to get rid of most of that material:

I finished the initial shaping with my Shinto saw rasp, and had this:

The front curve was somewhat tricky because it’s concave; I sawed a relief cut in the center and took out most of the waste with the drawknife and a chisel. (Note: Southern yellow pine is not particularly easy to use a drawknife on, but there’s worse.)

It came out as planned. Pay no attention to the ugly knots in the middle; those will not be visible with a cushion on top. I would have preferred clear wood, but due to multiple factors (the proximity of the nearest source of large southern yellow pine, the inconveniences of the source at the time that I went to buy it, not to mention the obnoxious process of picking through the pile alone on a steamy hot day in the middle of a pandemic), I settled for straight, mostly-quartersawn boards that would yield a clear perimeter, which is the only part of the wood that will be visible.

There isn’t much remaining work on the wood to do. I have to make the legs and the railing, do the final profile of the edge, and finish it. During finishing, I’ll make the cushion (hopefully I’ll have some sort of an idea about what I’m doing there).
