Kevin came up with a great idea on how to cut large curves in timber using a
router. By mounting an arm to your router you can make circular cuts much easier
than with a jigsaw or any other method.
Step 1: Measure the width of the router and mark out an arm at the same width
and to the required length. Remember the longer the arm, the larger the curve.
Step 2: Cut out the arm. Using the screw holes, screw the arm into the base
plate of the router.
Step 3: Measure and mark out plot points on the arm. You will use this for
different sized curves.
Step 4: Once you have decided how big you want the curve, screw the arm to
Step 5: Cut out the curve.
