Now we can take those dowels we have handy and start cutting them up.



We will need a number of 16" bars that we can screw in as cross sections in the cabinet. We will also need furring pieces (Dowels screwed to the inner sides of the cab to screw the cross sections into.The picture shows exactly how the furring works.



With those furrings cut and screwed into the cabinet, we can now assemble the parts. I did begin to paint much of the wood at this point, but that is unnecessary.



Notice how those front panels are placed on the front of the cabinet? The can be positioned however you want them to.



Each arm is made of two pieces of wood. One to go on the outside of the cab, and the other to bring it back flush with the inside of the cabinet. This is made from the remaining plywood.



You can size up how high you want your control panel. and clamp on the arms to test your placement. I chose 22 and 1/2 inches from the ground. Just line up and mark where to cut the arm pieces, make the cuts.



When you have the arms done, they can be bolted to the side. Just drill a hole in the arm and the side of the cabinet and slide the bolt through. I did 3 per side, and that was a style decision.
