I made this stencil awhile back so I could actually have some accurate angles and circle radius’ when I was doing quick 1:1 drawings while doing carpentry and metalwork.
Angle layout goes in increments of 4.5deg.
Circles start at 0.25in and step up in 0.125in increments up to 1in.
Can also be used as a square.
