I'm loth to call this a build thread, as it's very much in the design development/technical documentation stage. Hopefully it'll morph into a physical build in due course. What I intend to do is post my CAD drawings for the project here until such time as the physical work starts. There will probably be a few false starts, and consequent redesigns. The project is a '31 A with a fabric fixed-head coupé body, on a fabricated frame, z'd 6¼" in front and underslung at the back, on a 116" wheelbase. Apart from collecting parts (a process that happens haphazardly and without any structure as to the importance of the parts involved, so that I might end up with enough mirrors for six cars left over) the first job is to generate an accurate and detailed drawing of the frame, complete with all holes and brackets and tabs and lugs. I know that some of these will change when it comes to the actual build: the trick is to incorporate some allowance for variation at the other end of things to where they are critical. I've laid out the rails. Here's a .jpg-plot I'd taken a while ago. The drawing has since progressed quite a bit: I've since concentrated on the front end. Here's a front view: The axle is a fabricated tube axle. I've spoken to an acquaintance who owns a machine shop, and he is confident that he can do the 900mm CLR bend smoothly. The Mumford linkage will be behind and below the radiator. Note the roll centre height. Also shown are the single air spring and the cylinders for the hydraulic roll control system. The bell cranks are notional, as the longitudinal placement of all that stuff still needs to be finalized.
