PRACTICAL GEOMETRY - Lesson 3
The drawing of 'stepping off' is from Audels Carpenters and Builders Guide, NYC, 1923, p.640.
The holes in the daisy wheel are lower left, center, upper right. There are others which do not photograph as well. This sheathing board was given to me by the crew that deconstructed the barns. It travels with me when I present on Practical Geometry.
