I created this last weekend to make the box joints I showed in the previous post. This is mostly just a cross cut sled that I am using as a guide to cut the joint fingers. The runners are pieces of old oak hardwood flooring from my house. I need to make one more runner on this because the table is too short and one end keeps popping out.
Right now I am marking one side of the board to be jointed with some calipers, then eye-balling the mark on the table saw. I then cut the slots by making a cut on the saw, moving the piece over slightly, and make another cut, until the slot is finished. I then mark the other piece with that, and repeat the cutting process. Continue reading Box Joint Jig
The actual desk this brand new computer will sit in is yet to be completed. As of now, it is still an idea in my head, but I have been practicing the techniques I will need to construct this beast.
There will be three parts to this build, the desk top, the desk box, and the legs. Lets start with the desk top.
Since I don’t have many wood working tools, I wanted to build something that was simple to make on a table saw. I have a piece of plate glass that will fill in the center, then eight planks of wood will make up the frame around this.
The most difficult part will be to cut a ridge for the glass to sit in on the top pieces. The sides will be simple to cut, since the grove will span the entire length, but the ends will need to be cut only in the center. I believe I can cut the center on the table saw, then use a chisel to square out the corners.
Assembling the desktop will consist of gluing the planks in the shape shown in the drawing, with the long and short planks alternating. This should be strong enough with a good hard wood. I might round the corners with a bit of sanding as well. Its finished size should be about 28″ x 44″.
Small blocks of wood can be fastened to the bottom front to hold a keyboard tray underneath the desk for a better posture position. The keyboard tray will just be a plank of wood 1′ x 2′ 2″, fastened to metal rails to allow it to slide in and out (like my current desk).
The desk box is the thing I am practicing for right now. It will consist of 8″ wood planks, joined by box joints. It will probably be about 22″ x 44″ in size, smaller than the desk top so that the keyboard tray can fit.
I created a sled jig for my table saw to create the box joints. My third attempt is shown in the picture (the second attempt is at the other ends of that piece). I think it came out relatively well. I split one of the boards in half, but this is oak, which is really hard and not very forgiving. I am thinking of creating the final product with birch, which should be easier to work with.
I’ll show the sled and how I create the joints in another post.
Once the box is cut up, I will layout the computer pieces and create runners across the bottom. The electronics and water system will attach to these. I will also make a mounting point for the raising springs, which will also need to be modified to cross a larger gap (they will be attached to either end of the glass).
After looking at some other computer desks, I came to the conclusion that four legs is kind of boring. I’ve decided that I will attempt to create some cantilever legs with a diagonal front brace.
I believe I can make this with the table and hand saw I have. I will laminate three or more boards to create the legs, but leave some out to create a mortise. The diagonal brace will also be a laminated piece, with the tenon cut to fit into the vertical leg. I can then use the same laminating technique to create a box joint for the bottom feet.
