Hallo Rob, hallo dear paper friends!
I am working on a project involving a rather complex gear train. I would like to test the functioning of the gears without spending a lot of time with paper (that will be the final target...). I need a material easy to cut (possibly by means of the usual cutter) and sufficiently compact to ensure the test success. I tried a kind of polistyrene, but it tends to crumble..., so it does not work.
The gears have a diameter of about 15 cm, and a thickness of about 1-1.5 cm.
Thank you very much!
All the best!
