[TheForge] Slide rules (was: Excessive scaling?)

[Washington, Aubrey O.]

I think my grandfather had one of those.  He got his civil engineering degree from the Univ. of Texas in about 1905 and spent the next several years surveying the route for a railroad down the western coast of Mexico.  He left Mexico when the 1910 Revolution started.  I think one of my uncles got all his surveying equipment when he died in 1954.

Do any of you remember the rotary calculators, I knew some surveyors who
used them. They were also called coffee grinders, were basically a round cyl
1 1/2 or 2" in diameter about 3" long you dialed in a number on the case
then turned a handle on the end the number of times that you needed to
multiply.
