The final step is to attach the acrylic support legs. To fabricate the pieces needed, machining is required. Measure the diameter of the screws being used in the same manner as before for drilling the holes for LED’s. Ensure they are machine screws and not the pointy metal/wood screws.Once the holes have been drilled out, the holes need to be tapped using a tap and oil. This is slow process, and one needs to take care to not cause thread galling. The support legs attached to the lexan surface were rounded off by a grinding wheel to allow for a smooth rotation of lexan surface depending on desired viewing angle. Once all support pieces are complete, attach to lexan surface.
