After reading Jim Toplin’s “By Hand & Eye” I find myself moving further away from modern solutions and back to the old tools and ways. Fantastic work was produced hundreds of years ago by folks who were likely barely literate. A sector eliminates math and was used even before there were agreed upon standard measures.

I used a nice straight piece of maple so the markings would show-up easily. I started with a short one using 13 equal inches, but have enough stock to make one about 3 feet long after seeing what Oldwolf did with his.

I would use a more expensive hinge next time and maybe a thumbscrew on the long one to help keep it in place during measuring. Wood burnt markings finished with Benite wood conditioner.

Let no one who cannot think geometrically enter—- Plato (maybe)

Very nicely done.

This is a great tool. I may have to make one myself.
