Woodhaven 3260-3290: Large Circle Jigs User Manual

Page 4

USING THE CIRCLE JIG

Install your router/bit on the router plate. The Circle Jig

is designed to be mounted on top of the work, or at the same
level as if it were on top of the work. Drill a 1/8" pilot hole
1/4" deep in the work for the Pivot pin to set in. If you prefer,
you can remove the pin and drill & countersink the Pivot, then
use a flat head wood screw to connect the Pivot to the work.

If you don’t want to drill a pilot hole in the work, double

stick tape a 1/2" thick spacer to the work and drill the hole
in it. You need to compensate for raising the Circle Jig 1/2"
by making a 1/2" thick spacer to place between the Double
Track and the Router Plate (3260 & 3270) or between the
Router Plate and the Plate Spacer (3280 & 3290). You’ll need
to swap the 3/4" screws for the 1-1/4" screws (MF020).

The Cursor reads the RADIUS of the circle on the tape

measure and you need to double that measurement to get
the DIAMETER. Make sure to re-adjust the Cursor if you
change bit diameters. Measure from the cutting edge of the
bit to the center of the pivot pin and adjust the Cursor so you
can read this dimension on the tape measure. See fig. 12.

ROUTING & DRAWING

Insert the pivot pin in to the pilot hole. Loosen

the ratchet handle and slide the bracket along the track
to the dimension desired, then tighten the handle.

When cutting the inside edge of a circle, swing

the router clockwise. When cutting the outside edge
of a circle, swing the router counterclockwise.

Insert the pencil holder (3200D) in the bit opening of the

router plate, insert a pencil (with a blunt point - like a golf pencil)
in the pencil holder to draw the desired circle. See fig 13.
