Materials:
4x 2x6 KD "whitewood"
2x 2x4 KD "whitewood"
4x 3/8 5" bolts
8x 3/8 washer
4x 3/8 nuts
1x Dark Walnut stain
The first thing I did was rip the rounded edges and plane all of the lumber to a consistent thickness. Then I laid everything out and made sure it fit snugly, using a hand plane to clean up areas where everything didn't fit together snug, and proceeded to glue. I only had 36" bar clamps (total width is 42) so I glued the large piece and then the short piece (which will make the curve) separately and then glued them together last.
Once the glue dried I ripped the ends with a circular saw so that everything was perfectly flush, cut a notch from the back corner at 45' (to give a good place to mount the monitor arm) and then when we (friend pictured) drew an arc using a pencil taped to a dowel.
After cutting along the line with a Jig Saw and using a roundover bit on the router to clean up the edges:
Repeat for the other leg, and then it was time to figure out how to attach the legs to the table top. I decided to use cleats, which were tricky to install. Becuase of my offset half-lap I assembled the legs and the cleats, THEN glued and screwed the cleats the table. once the screws were down I removed the legs (this ensured I had perfect spacing for my legs), and then clamped everything down.
Once the glue dried I test fit everything and put it on the ground to make sure everything set square. Unfortunately two legs were 1/8" too long so I flipped the table over, marked off the 1/8th" and used a belt sander to get the legs the right length. Fortunately this desk is going on carpet so the bottom doesn't have to be absolutely perfect to sit on the floor.
To stain it I used a dark walnut stain. I removed the legs from the top, stained them first, followed by stained the bottom, avoiding standing too close to the edges so that when I stained the top I wouldn't end up applying stain to a visible face twice. Once it was dry I flipped the top and stained the top and edges, as well as the 1" of the bottom I left unstained previously.
Finally I applied 3 coats of polyurethane and brought it in the house.
I'd take an after picture but... she buried it in crap and I'm too lazy to clear it off.
The desk is a bit wobbly length wise, but very sturdy the other direction. The mounting mechanism for the legs isn't very strong, I'd recommend coming up with a better solution.
