Up until now, the side with the trigger unit and cam has been "the top." Now it's "the bottom." The face of the plywood chassis with the axle sticking out of the middle is now the top. This is the front panel of your control box. For the build model, I cut the breadboard to its final size, and added 1¾" bottom, side and end panels to it. Nothing fancy, everything was cut from ¼" plywood, butt jointed, with ¾" x ¾" x 1½" blocks in each corner to strengthen the joints and give me a place to sink the base attachment screws. I skinned the top of the box with 1 / 8 " thick slats salvaged from an wooden orange crate to cover up the ravaged surface of the breadboard plywood, redrilled the axle hole and sanded the bejeezlies out of the whole lot. Once stained and finished, the result had, um, a lot of personality. Controlling the Controls Control box? Check. Control mechanism? Check. Now you need a control interface. Usually, this would call for a knob, but given the friction vector we just bunged into the mechanism, it'll need to be a truly grip- worthy knob, or (back to the whole mechanical advantage thing again) a lever. I know! How about a lever with a knob on it! 338
