Petey, you were right. I re-read that section and there was even more missing content than I realized earlier.
I have added the missing bits. I went back and re-read the whole article and I didn't talk enough about the bushings used to connect the two auxiliary fences together. That has been corrected.
I also did not talk about (but see no reason to add unless there is demand) how the ruler (be it Starrett or Mitutoyo) magnetically attaches to the fence/body to act as a gauge for the fence. It's rather uninteresting and can probably be discerned from the photos already provided, but if anyone is interested, I can describe it.
