Scribing Large Circles
H
ERE’S AN INEXPENSIVE ANDeasy-to-make alternative to trammel
points for scribing large circles or arcs. First cut a long hard-
wood beam to fit the hole in your marking gauge. Make a vertical
sawcut in one end of the beam, and drill a^9 ⁄ 32 -in. hole through the cut
to hold a pencil. Now, drive a brad in the bottom of the gauge to
serve as a compass point, install the beam in the gauge block, and
you’re ready to scribe a circle as big as the beam.
