08/ROTATIONAL STOOLS
Now that you’ve learned what goes into setting up a CAM
file, you’re ready to cut a pair of Rotational Stools. The fol-
lowing pages take you through the basics of digital techni-
que, where the precision of the digital file meets the physical
variability of material, fabrication, and assembly. This first
project shows you how to create tight-fitting joinery by
putting the basic concepts of measuring material and scal-
ing files into practice. It also walks you through how to evalu-
ate fit, and it offers simple techniques for assembly, drilling,
and fastening.
