4.Plywood Blade: Used for cutting plywood or veneers. A 14" plywood blade will have 80+ teeth, a steep alternate top bevel tooth pro- file and very shallow gullet. See Figure 34.

5.Thin-kerf: Most types of saw blades are available in a thin-kerf style. Used primarily to minimize stock wastage. It is recommend- ed thin-kerf blades be used in conjunction with a blade stabilizer to reduce blade wob- ble. Note: Most blade guards/splitters are thicker than most thin-kerf blades. Make sure the stock will pass by the guard/splitter before beginning a cut.
6.Dado Blades: There are two types of dado
blades: stack and wobble. Stack dadoes are expensive and time consuming to set up but leave a clean and smooth finish. Stack dadoes are used for fine furniture and cabi- net making. Wobble dadoes are inexpensive and easy to set up, but leave a rough finish.
7.Moulding Heads: A moulding head is a cut- terhead that attaches to the arbor and holds individual moulding knives. We do not rec- ommend their use. They are very dangerous and required training beyond the scope of this manual.
This section on blade selection is by no means comprehensive. Always follow the saw blade manufacturer's recommendations to assure safe and efficient operation of your table saw.

Crosscutting
Crosscutting means cutting across the grain of the wood. In wood products without grain (i.e. MDF, particleboard) it simply means cutting across the width of the stock.
Crosscuts are made with the miter gauge. There are two miter gauge slots in the table top. Use the one that works best for the piece being crosscut. To make a crosscut using the miter gauge:
1.Inspect the board for soundness. You do not necessarily need a square edge to crosscut with accuracy.
2.Inspect the miter gauge. Is it properly set and tight? Move the rip fence completely out of the way.
3.Turn on the saw and allow it to come to full speed.
4.Hold the workpiece firmly against the face of the miter gauge and ease it into the blade. See Figure 36.
5.Turn off the saw and allow the blade to come to a full stop.
