So you need to cut a few biscuit grooves but don’t own a biscuit joiner – No problem, cutting the grooves with your router and a slot-cutter bit is easy. If you can’t afford a $200 or so biscuit joiner, then a router and a $40 biscuit joining router bit set is a real money saver, assuming you already own a router.

Here’s how you can use your router with a straight bit to plane wide material: Mount an oversized base plate on your router and screw the base plate to a pair of stiff, straight “Stretchers.” Make your stretchers at least twice as long as the width of the workpiece, plus 8 in.

Remember, when you are cutting wood with a router table the flow of the wood wants to go from right to left, this means you are forcing wood into the cutting path of the bit just as you force wood into the cutting path of a table saw blade. If your wood has a bow or twist in it, you need to make an extra effort to get that wood flat against the router table top as it enters the winged cutter.
