Morris, your solution was much more elegant and professional looking
than anything we ever did. Downright impressive.

Our was a lot more primitive... say like... ummmm the Lee Valley jig
for instance. I don't remember what they used to call the small
versions of the framing squares, but that sure looks like what they
have. A square, screwed to a piece of wood. The "guide" was the edge
of the square, and that was it.

Comparing yours to that is like comparing a racehorse to a mule.
