CIRCLE CUTTING
See Figures 13-16.
The circle cutting jig makes it possible to cut and shape
circular patterns in both large and small stock. The smallest
circle that can be made is approximately 8 in. in diameter.
Note: There are many variables that influence the size of a
circle being cut or shaped. The set-up you make, the location
of the circle cutting collar, whether you drill a hole and use the
machine screw, or whether you use a wood screw are a few
examples of factors that influence the size and shape of a
circle.
CIRCLE CUTTING COLLAR
See Figures 13-16.
The circle cutting collar mounts on the bottom, center of
workpiece, with either the machine screw and washer or the
wood screw supplied. It then mounts on the sliding miter table
in one of the two holes used for the locator pin on the bottom
of miter fence (The operator's manual for your BT3000 refers
to them as hole "A" and hole "B").
CIRCLE CUTTING SET-UP WITH MACHINE
SCREW
See Figure 13 .
To make set-up:
1. Drill a 3/16 in. hole in center of workpiece for machine
screw.
2. Place the machine screw and washer thru the top of
workpiece.
3. Secure to circle cutting collar on the bottom of workpiece.
Note: Slotted end of circle cutting collar should be
turned away from workpiece as shown. A screwdriver
can then be used to tighten screw securely.
4. If applicable, drill pilot hole in workpiece for jig saw
blade or router bit.
CIRCLE CUTTING SET-UP WITH WOOD SCREW
See Figure 14.
To make set-up:
1. Place workpiece upside down on a flat workbench.
2. Locate center of workpiece as shown in figure 14.
3. Place #6 x 1 in. wood screw thru circle cutting collar and
thread into bottom of workpiece. Note: Check thickness
of workpiece before threading screw into workpiece.
Be careful not to let screw penetrate top surface of thin
workpieces.
4. If applicable, drill pilot hole in workpiece for jig saw
blade or router bit.
