some machine work






photo 1) New nuts for the rear suspension inner fulcrum shafts machined from 7/8" (22 mm) stainless hex rod and new stainless spacers for the upper mounts on the rear sub-frame cut from stainless tubing.

Photo 2) Front sub-fame bolted in place ready to accept the flip-up nose section. The whole nose pivots around the bolts at the front corners which carry bronze bushings and nylon washers. The aluminum panels mate to other panels in the nose to duct air to the engine air filters and the radiator which rides, almost horizontal, on the front sub-frame.

photo 3) Pip-pin latch at left rear corner of nose section (bonnet).

photos 4 and 5) Since the car is a spare time project, it's jammed, out of the way, into a back corner of the shop. It's time to get the rear body-work mounted but I'm sort of stuck until I can get some help turning the car around. In the mean time I needed something else to do so I machined these two pieces out of aluminum bar stock (6061 T6) to hold a boot around the U-joint in the steering shaft where it passes through the fire-wall. One piece (with the larger center hole and mounting screws) will bolt to the fire-wall and the other piece will ride on the lower steering shaft - the shaft will turn inside the center hole. The boot will be right over the left exhaust header pipes so I'm making it out of foil backed, fiber-glass insulation cloth. That's the plan anyway.
