But the shortest possible explanation I can give is, that the use of logarithms is to enable someone to MULTIPLY numbers by ADDING their logarithms looked up at a precalculated table, and looking up the number accompanied to the addition's result at the same table (divisions are made by subtracting logarithms). The basic principle of that AR calculator, and explaining the principles of logarithmic scaling are beyond the goals of this article - I propose the interested ones to look up Wikipedia or a good maths book for 'slide rule' and/or 'logarithm'. Just be as precise as you can achieve, and do NOT use less effort as when making a fine piece of maille - using ruler and knife for cutting may be a good idea. So you might be forced to make corrections or even a repetition of the print and cut, until it works out well. The slider should be relatively easy movable, but without any wobbling, as that would destroy the principally high precision of this tool. to imagine this - but I guess these would be unable to use this tool at all, so I don't worry too much about them). Then stick the slider into the body, so its scales are visible through the slots (I note that, because some people seem being too d. After gluing the body part, you may cut notches at its left and right ends to be able to push the slider easier out of its centered 'parking' position (as shown above) - or simply cut the body a bit shorter, if you like to do so. 160gsm (~8 mils thick) strong paper or maybe light cardboard (letter or A4 format preferred, just check 'fit to page' to get the largest possible result), you should cut out, separate parts, fold and glue the item together, as noted on the left margin of that page. Note: Scroll down to the bottom - there is a link to the newest version of this AR calculator, incorporating changes made after original submission of this article.Īfter printing the slide rule page on approx.

As this enhanced version has undergone significant changes and additions compared to the basic version provided by 'Workshop Warlock' in his article Aspect Ratio Calculator, I will provide a new manual now, that shows and explains these changes - for the basic explanations please follow the instructions of my forerunner, as they are not only sufficient, but excellent.
