    I have made an 10cm quare and measure it and report the measure on the circle, then the same thing for 1cm, 5cm and so on.

    Where do u get the circle to measure the centimeters

  11. Nico71 says:

    Yes you can, but you may draw the dial to obtain the good scale. You can also change the gearing without changing the dial but modify the lenght of cursor. Regards

    This is a great device! Thank you for instructions. One question: can I substitute the big 40 teeth gear with something else? I don’t have such a big gear..

    I like this a lot! Prior to AutoCAD and other virtual drawing tools, using planimeters like these were THE WAY to quickly determine areas. I remember using a device like this. Thanks for sharing!
