Jig and Workpiece Setup
Recommended maximum material thickness (for through routing)
is 1/2".
1. Attach your compact plunge router to the Jig Arm (1) with the
included 10mm Pan-Head Machine Screws (8) and install
the desired bit.
Note: We recommend using a 1/4" diameter spiral up-cut
bit (82652, sold separately).
2. Set up your workpiece on a solid, stable surface.
3. If making through cuts, elevate your workpiece to prevent
damage to the surface underneath. Secure the workpiece
to a sacrificial board, or use spacers to hold and support the
workpiece, including any sections that will be cut free. Make
sure that all parts of the workpiece will remain stationary
during cuts to avoid potentially dangerous and damaging
shifts, and position any spacers out of the path of the cutter.
Routing an Ellipse
1. Mark a center point on your workpiece. Lay out the
major (long) and minor (short) axes of your ellipse so that
they’re perpendicular and intersect at the center point. The
major axis can be a maximum of 24" long and a minimum
of 11". The minor axis can be a maximum of 19" long and a
minimum of 6". (The maximum difference in length between
the major and minor axes is 5".) Fig. 1.
2. Use the scribe lines machined into the Jig Base to center it on
the intersection of the major and minor axes. Secure the Jig
Base (2) to the workpiece with the included #6 Wood
Screws (7). Fig. 2.

3. Insert a Dovetailed Key (3) into each channel in the Jig
Base (2). Center one (hereafter referred to as “Dovetail
Key A”) along the minor axis.
4. Loosen the two Locking Pivots on the Jig Arm (1) and position
them so they mount on the pins in the Dovetailed Keys (3).
Fig. 3.
Note: The Locking Pivot closest to the router must be
mounted on “Dovetail Key B” (along the major axis).
5. Rotate the Jig Arm (1) so it’s aligned with the major axis, and
adjust it in or out until the bit is positioned as desired to make
the cut. Tighten the Locking Pivot on Dovetail Key A. Fig. 4.
6. Rotate the Jig Arm (1) so it’s aligned with the minor axis, and
adjust it in or out until the bit is positioned as desired to make
the cut. Tighten the Locking Pivot on Dovetail Key B. Fig. 5.
Note: The maximum distance between Locking Pivots A
and B is 21⁄2".
7. With the router off, rotate the Jig Arm (1) through the full
range of cut. You want to ensure that the dovetail keys will
move smoothly, as well as verify the ellipse pattern and proper
placement of any spacers/supports. Then make the cut.
Note: Don’t try to cut to full depth in one pass. Make several
passes, increasing the depth of cut with each pass.
Routing a Circle
1. Mark a center point on your workpiece and lay out the
perpendicular axes.

2. Use the scribe lines machined into the Jig Base (2) to center it
on the intersection of the axes. Secure the Jig Base (2) to the
workpiece with the included #6 Wood Screws (7).
3. Remove one of the Locking Pivots from the Jig Arm (1) and
one of the dovetail keys (3) from the Jig Base (2).
4. Make sure the remaining Dovetail Key (3) is in the channel
that has the two holes near the center. Align the holes in the
Dovetail Key (3) with the holes in the Jig Base (2) and secure
with two of the included #6 Wood Screws (7). Fig. 6.
5. Loosen the Locking Pivot on the Jig Arm (1) and position it so
it mounts on the pin in the Dovetailed Key (3).
6. Adjust the Jig Arm (1) in or out until the bit is positioned as
desired to make the cut. Tighten the Locking Pivot.
7. With the router off, , rotate the Jig Arm (1) through the full
range of cut. You want to ensure that the Jig Arm will
move smoothly, as well as verify the circle pattern and proper
placement of any spacers/supports. Then make the cut.
Note: Don’t try to cut to full depth in one pass. Make several
passes, increasing the depth of cut with each.
