I was lucky enough to find some 7075-T651 aircraft aluminum plate, still with the Martin Marietta markings on it. Very useful for miscellaneous parts like this ECU mount. That stuff is strong! Almost as hard to bend as steel, but it makes for a very stiff end result. So I just cut this blank out of the aluminum plate, bent it in my hydraulic press, and added lightness using the milling machine. It mounts to the frame with aluminum clamshell mounts purchased on Ebay.
Yet another video update. Here you’ll get a tour around the car pointing out the newest additions, followed by fabricating the fuel swirl pot and mount, the first power-up of the electrical system, mounting components on the instrument panel, drilling the firewall for fuel lines, fabricating braided stainless steel fuel lines, building and installing the throttle pedal cable pull rod and the cable itself, building the ECU mounting platform, and machining the rear sprocket to fit the differential.
