I have been in need of a small drafting board that I can use at my workbench. So I made one. The walnut and maple square hugs the sides of the board and stays parallel while still sliding easily. Thumb screws in the feet pinch the board holding them in place. The feet can be removed for storage as well as flipping the board. This way you can use either side. Small brackets hold all three pieces on the wall when not in use.
