Some time ago, I installed a Crane XR700 electronic ignition in my bugeye. I've never been really happy with the plastic shutter that comes with the kit--to make a long story short, it just doesn't fit right, and the poor fit could lead to significant mistiming of all cylinders except no. 1.
Last week it was really too hot to do much else, so I got busy with my lathe and made a new shutter out of aluminum to replace the plastic one. This new one is accurate to a couple mils in all important dimensions; it's probably more precise than the distributor itself. Now that it's installed, it fits perfectly. No eccentricity at all. A really fun project.
Pictures below. Not shown is the fact that I colored the aluminum shutter black, with a felt-tip pen, to prevent any problems from reflections; it's an optical device, after all.
Got out today for a test drive. It was a beautiful, 70-degree sunny day in S. Cal, and Ruby Redcar hummed along beautifully, cruising down Pacific Coast Highway to Newport Beach. Several compliments and thumbs-up gestures (yes, it really was the thumb); one from a guy driving a new Porsche Carrera.
