gift idea - kitchen rule #2: scale glue-up - first try and usage example
Having printed the scale here is the result of, in fact, my second glue-up tentative: I had to scrape the first one. This 2d one is ill centered.I glue the complete scale as a single piece of paper and I cut the two sides of the center rule afterwards. This ensure the bottom scale and the upper scale are aligned.I will tweak the scale with the drawing programme to make the positioning easier. here with an example of usage for unit conversion: You will notice I have reproduced the original scale with fraction numbers on the bottom scale.
