I was thinking about making myself a traveller. I was wondering if there was an easy way to layout the graduations around the circumference?
Obviously there is a direct correlation between the diameter and the spacing.
For those who don't know a traveller is a wheel with a handle and a pointer, as you roll the wheel you count the full revolutions and the the stop point on the spot on the wheel and calculate the distance travelled. Large modern versions are used in serveying, in the old days they were a hand tool used by blacksmiths & wheelwrights, possibly others.
