Cutting Curves

NOTICE

Refer to Figure 36 on page 29 to determine the best blade for cutting various curves.

When cutting curves, simultaneously feed and turn the stock carefully so that the blade follows the layout line without being twisted. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, use either a narrower blade or a blade with more teeth-per-inch (TPI). A blade with more TPI can cut relatively tighter curves, though the cut is usually rougher than cuts produced by a blade with a medium amount of TPI.

Always make short cuts first, then proceed to the longer cuts. Relief cuts will also reduce the chance that the blade will be pinched or twisted. Relief cuts are cuts made through the waste por- tion of the workpiece and are stopped at the cut line. Make relief cuts from the workpiece edge to points along the cut line where there are sharp changes in direction. As you cut along the layout line, waste wood is released from the workpiece, alleviating any pressure on the back of the blade.

NOTICE

Relief cuts require you to back the blade out of the cut. Make relief cuts as short and straight as possible so the blade only has a short distance to back out.

Stacked Cuts

Before making stacked cuts, make sure both the table and the blade are square to one another. If the table and blade are not square to one anoth- er, the cut-out workpieces will not be the same size.

To perform a stacked cut:

1.Draw the project cut lines on one of the work- pieces. There should be at least an inch of scrap area around the outside of the project cut lines.

2.Stack matching sized workpieces on top of one another.

3.Secure the workpieces to one another with hot glue on the sides of the workpiece or brads in the scrap area on the outside of the project cut lines.

4.Draw relief lines where the blade or work- piece may become strained when cutting. Refer to the previous sub-section, "Cutting Curves," for more information on relief cuts.

5.Make all of the cuts on the relief cut lines.

6.Cut out the final shape of the workpiece by cutting along the project cut lines as shown in Figure 34.
