General (the company that makes rulers, dowel jigs, etc, not the CN
green iron folks) makes a compass that is fairly robust, has a
threaded cross rod with a nut, and works better than the grade school
compasses you can get for $1.50 at OfficeMax or Walmart. I paid $5
for mine a few years back at a wood show. I think Lowes or the Borg
carries the line.
