Before cutting my final material I made some tweaks to the Vectorworks design. I added 0.02 inches to the thickness of the slots (I figured it would be better to go a little too loose than not fitting at all), as well as some dog bone corners in areas that I’d overlooked before:

3-ply Canadian birch from Midtown Lumber. I might have been ripped off but this costed me $96 for a 4’x8′ sheet. That’s how confident I was in my design and prototype. I had half of the sheet cut into two 2’x4′ pieces, and finished the table in two cutting jobs (as per the designs above):

The sheet corners ended up being pretty accurate right angles, so my cuts went very smoothly. Took about 45 minutes from start to finish, including changing boards. Here is the first cut, the surface and support beam:

The two identical legs:

After sanding:

Assembled (requires no screws or pegs — it’s completely detachable):

Sadly the table is structurally weak — the legs are too thin, the slots are actually a little too loose, and the joints which the legs attach to the table surface aren’t designed in a way that provides them with enough side-to-side integrity. I’m not sure why I had so much confidence in my design when I’d never actually built a piece of furniture in my life. I still think this piece is salvageable though, perhaps with diagonal support beams between the legs.
