The fabrication of the walkthrough partition continued with the addition of ribs to the sheet metal installed yesterday. The ribs add strength to the otherwise flat sheet metal, preventing the panel from resonating while the bus is running. These ribs would have originally been pressed into the panel by a machine twice the size of the garage the bus is being restored in. Since I don’t have one of those, the ribs are being recreated by welding in a section of sheet metal bent into a “C” shape.
