I've been putting off working on this thing for a year, but have recently gotten to the point where I'm going to be sealing it. I had the idea to make a sturdy desk from a slab of wood because everything that wasn't MDF was very expensive. I ended up settling on a sheet of baltic birch ripped in half and glued together. The 5'x5' turned into a perfect 60"x30" desk size. For the legs I used T-nuts countersunk into the bottom board and sealed in when gluing the two halves together. Now I have a table with mounting hardware built in, and very sturdy. Just today I finally got around to using a flush cut bit for the router to even out the overhang from the rough cut the lumberyard did to cut it in half, and then used a 1/4" rounding bit for the router to make a more comfortable edge. Does anyone here have any constructive input on what I've done so far, or ideas on how best to make a durable desk surface? I plan on using polyurethane coats, but I'm up for suggestions.
