Other slide rule sites

The potential uses of slide rules go far beyond those described on this site. The potential can be extended in two ways:

  • Use of the scales described on this site for more complicated calculations.
  • Use of other scales not described on this site.

I have tried to include the date of the most recent update of the sites listed below. Sometimes this was not easy and I had to estimate from other clues in the text. If I have misrepresented your site in any way or if you have a site that is not included please contact me at ron01@sliderules.info .
