Assemble the study desk using biscuit joinery and nails. To ensure a good job with a biscuit joiner just make certain you are holding it flat and tight against the bottom and front surfaces before making the cut.
The drawings show the location of the biscuits and the easiest way to cut the biscuit slots is to use the biscuit joiner without the fence. For those of you unfamiliar with the Biscuit Joiner I’ve written a book on how to use it for all kinds of joints. You can check it out at
Start by marking the location of the biscuits on the parts. Parts A, B, and C should get biscuit slots. Place both parts A face down with back edges facing each other on your work table. On each part A, measure 1 inch back from the back edge. Beginning from the top, make the mark is 12 inches long. Part B fits here. Place part B face down on the work table with the top edge against the top of the parts A. Move part B on top of one part A with the edge on the 1 inch line. Clamp it down to part A and the work table. Mark four biscuit slots on the surface of part B. Using the biscuit joiner upright on the marks, cut the slots into part A. Place the base of the biscuit joiner on part A and the face on the edge of part B, cut the four biscuit slots.
Unclamp part B and move it so the other end is on the 12 inch line on the other part A. Clamp part B down to part A and the work table, then repeat the marking and cutting of the biscuit slots. The two photos below show the biscuit joiner in the two positions used to cut the biscuit slots.
Cut the biscuit slots on the ends of part C, and the inside of parts A similar to the previous steps with part B. With parts A on the work table, measure 3 ¾” from the tops of both parts A. Make a 6 inch line, with a square, beginning 1 inch from the front edge of each part A. This is the location of part C.
Place part C on the first part A with the end on the side of the line facing the top of part A. Clamp part C and part A to the work table. Make two marks each 1 ½” from the front and rear edge of part C for the biscuit slots. Cut the biscuit slots in part C and part A just as you did for part B. Unclamp and move part C until the other end is on the line on the other part A. Clamp part C and part A to the work table. Mark and cut the biscuit slots on this end of part C and part A. You are ready to assemble the study desk.
Assemble Part D to the top of Part C in the center and flush with the front. Use a square to make certain that Part D is square with Part C and then nail these parts together. Since this is the bottom and not visible, you can also drive a couple of 2” drywall screws for extra strength.
