Geometry & Design: The Sector - A First Look
Channel: Plan B Workshop
Date: 24/03/2020

This video introduces the second unit of the Geometry and Design Series. In it, I briefly demonstrate how a sector can simplify the task of dividing a line segment into parts that satisfy a given ratio.  While we've already learned how to do this using a compass and straightedge construction, it is much faster to perform the task with a sector. 



There are a few ways you can obtain a sector for your own use. 

1. Jim Tolpin and George Walker offer a printable sector on their site "By Hand & Eye": https://www.byhandandeye.com/product/580/
2. First Light Works has also made a printable paper sector available for free: https://www.firstlightworks.co.uk/post/coronasector
3. Acer-Ferrous Toolworks has a professionally constructed, full sized layout sector available for sale.  It might be worth considering if you are wanting to go all in on pre-industrial design: https://redrosereproductions.com/sector/
