The Family Handyman
Build this compass/ruler to trace every curve a project throws you. You’ll need:
■ Pine (3/8 in. x 1-1/4 in.) stop molding ($3 at a home center)
■ 5/16-in. locknut
■ Six-foot self-stick measuring steel tape (Starrett No. 64188, $10, from Rockler)
■ Epoxy and one eye screw
Apply the steel measuring tape along one edge of the molding, beginning 1/2 in. in from the end. With a square, draw hash marks above the tape every half inch, then trace a horizontal line through the hash marks to create center points for drilling. Drill 1/16-in. holes through the center points for the screw pivot. Mark and drill a 5/16-in. hole centered on the “zero end” of the tape, then center and epoxy the 5/16-in. locknut over the hole. Cut a curved shape at the end around the nut.
That’s it. When the epoxy is dry, just thread a pencil into the nut, screw a drywall screw at a desired radius and start your circles. Thanks to Alice Wagner for this tip.
