Calculation and measurement tools

Those who wish to prepare copies of the tools that are part of Mathematicus can download the files and print them on paper or – better – on A4 or similar format cardboard.
Once they have been cut out and the central hole has been made, they must be assembled with a brad or rivet, as shown in Appendix 2 of the book. The Quadrant has no revolving parts, but a thread and a small weight (plumb bob) must be applied.
