A bit more sheet metal work is in order. The front facade is necesary for both aesthetics and functionality. It helps to stiffen the frame in addition to enclosing the electronics. Made from the same 22 gauge mild steel used for the frame. Liberal use of machinist blue was needed for scribing the lines for the sheet metal brake.
The front is then marked with a Sharpie for the area of material needing removal in order for the arms and platform to operate. Holes were drilled at each corner, then a nibbler was used to follow the lines.
Finished with the sheet metal. The facade neatly encloses all the electronics.
