Drilled and tapped for the screw and drilled a clearance hole for the mount bolt.At 20 threads per inch, that would be .050″ per turn. So .01″ would be 1/5 of a turn. Put on a standard six-flat nut for reference. Turn less than one flat would be .050/6 = .0083 inches, a little margin to the spec.
So, to use it, you spin and gradually drop the screw until it just touches at the highest point. Turn to the lowest point, and tighten down. Took less than one flat, so I believe I am in spec!
In this clip from FMCG, Ken responds to Jeri’s capacitor deconstruction with his own very visual (and very mechanical) demonstration of how voltage is generated and how you can build a simple capacitor, with aluminum foil and plastic, to generate charge mechanically and dump it into the cap (analogous to how a Wimshurst machine works).
