Using the Trammel to Cut Circles

The optional circle cutter (trammel) permits the jigsaw to cut circular holes in a workpiece from the minimum and maximum sizes shown in the table below.

The optional circle cutting trammel attachment mounts to the underside of the optional guide rail base (see page 10). The circle cutting attachment contains the following features:

►► Built-in tape guide showing the cutting radius from 46 mm to 1500 mm.

►► Clamping knob to lock the trammel at the desired radius.

►► Index pointers and trammel points for either right- or left- hand mounting to the jigsaw base.

►► Trammel points for either clockwise or counterclockwise cutting directions.

►► Trammel point pin with on-tool storage location.

1.Identify the location of the center of the arc or circle you wish to cut.

2.Drill a 4mm (5/32") hole at the center of the arc or circle.

3.Loosen the clamping knob and extend the tape measure until the index pointers are pointing to the desired radius. The radius is 1/2 the diameter of a circle.

4.Retighten the clamping knob.

5.Insert the trammel point pin through the trammel point of the circle cutter, and into the hole you drilled into the workpiece above.

►► There are 2 trammel points on the circle cutter. One is for clockwise rotation and the other for counterclockwise rotation. Use the trammel point that is directly across from the sawblade when the circle cutter is mounted to the jigsaw.

6.Install the desired sawblade into the saw. If the radius/ diameter of the cut is small, use a scrolling sawblade. For larger diameter circles, the high side set teeth of the FSG blades will probably work best.

7.Install the guide rail base on the saw as described on page 10.

8.If you are cutting a full circle, you will need a starting point for the sawblade that lines up with your circle.

a.Using a pencil and the cutting indicator, trace out a portion of the circle where you will manually begin cutting.

b.Drill a hole on the waste-side of your circle large enough to insert the sawblade into.

c.Use this starting hole to manually begin cutting the circle—just enough to get the sawblade lined up with the cut.

9.Place the jigsaw onto the circle cutter and continue with the cut.

10.Before completing the cut, make sure that both the waste piece and the saved piece are supported.
