Using the Sector

The sector can be used to calculate numerous mathematical problems without using conventional mathematics.  It’s simple to use, and after a shallow learning curve, users will be able to quickly and accurately solve common woodworking problems with confidence.  The sector comes with an illustrated instruction booklet for learning the different scales, and we also now have a series of videos showing its functions.  They can be seen on the sector page, or on our YouTube channel.  The sector may be purchased here.
