  • Does this mean anything to anyone?

    7° 7' 36".
    3.2505

    I have a white board next to my desk and that is written off to the side.
    Trust me, I did NOT do the math so it had to be something I copied.
    I don't have gage blocks so it couldn't be something I was going to machine.
    Ring a bell with anyone?
    It just looks so important I don't want to summarily erase it.

      I was thinking maybe taper per foot and consequent degrees, but it doesn't work out. Close but not quite. 3.2505" TPF is a 7°42'47" half-angle.

        That's Latitude coordinate N or S, but I use them in a different format, and with a Longitude. It's incomplete, probably a temporary note for someone.

              7⁰ North could place you on the Panamanian southern border.

                And he doesn't like to have things placed upon him...

                border - the part or edge of a surface or area that forms its outer boundary

                    I searched 7° 7' 36" in Google and it brought up some biblical stuff about a sinful woman.

                      Cosine is .992.

                      Almost one. (One foot, one inch, whatever. Or one thou.)

                      Compound rest set to seven degrees, (or thereabouts) and it will move in fractions of a thou relative to the work.

                      It's how I sneak up on final OD.

                            If you're so young you don't know then I can't begin to tell you. :-) During WWII that and the corresponding sketch was seen everywhere. :-)
