A compass is often used as a symbol of precision and discernment.
I like to use a compass for woodworking, the points make it easy to get precise measurements and for marking distances repeatably and very accurately. It has a spring action all made from wood and a fine adjust screw.
This is a very simple woodworking project and one that I will certainly use often. The reach is slightly over 1 foot. I really like many different measuring tools and this one is a keeper. An easy woodworking tool that can be made in less than 1 hour.
