*The slope of the stock's face, as measured from horizontal. t For the proper saw arm setting, subtract the angle shown on the chart from 90".

Miter Jig

If you make many miter cuts, you may tire of constantly readjusting your miter gauge to the proper angle. Instead, you can set this jig to any angle between 70 and 30 degrees (approximately), then leave it so it's always ready to go. And if you regularly cut several miter angles, build several jigs and set each to the appropriate angle.

The sliding table is made of medium-density fiberboard (MDF), with two acrylic plastic runners that ride in the miter gauge slots, guiding the jig's table back and forth across the table saw. Two adjustable fences, one for making left-facing miters and the other for right-facing miters, back up the stock as you cut it.

Router Circle Cutting Guide

JL Rout the curved slots in the adjustable fences with a router and a Circle-Cutting Jig. This simple jig is a piece of V-f-inch plywood cut to fit the base of your router. Drill a vVinch-diameter pivot hole in the plywood, 9V4 inches from the router bit. Rout the slot in several passes, cutting Vs inch to V-t inch deeper with each pass.

jbmf Place the jig on the table saw so the runners fit in the miter gauge slots, and cut a saw kerf in the sliding table. Do not cut all the way through the table. Stop the kerf just past the fences. Turn off the saw and use a drafting triangle, square, protractor, or sliding T-bevel to adjust the fences. Afterwards, make several test cuts with each fence to ensure it is set properly.

You can make a rabbet with either a table-mounted router and a straight bit, or a table saw and a dado cutter. For either setup, use a fence to guide the work. Adjust the width of the rabbet by changing the position of the fence relative to the bit or cutter. Adjust the depth by changing the height of the bit or cutter above the table.

Cut a rabbet in a test piece, feeding the wood past the bit or cutter. (Remember to feed the wood against the rotation of the cutting tool.) Measure the width and depth of the rabbet and, if necessary, adjust the position of the fence or the height of the cutter. Then cut the good stock. (See Figures 3-6 and 3-7.)

You can also use a table saw and an ordinary saw blade to cut a rabbet, but this requires two passes and — almost always — two setups. Cut the larger dimension first, then the smaller. Since you must* perform this operation without the saw guard, this sequence will leave less blade exposed when the waste stock falls away from the work piece. (See Figure 3-8.)

3-6 To cut a rabbet, feed the board past the bit or cutter, keeping it pressed against both the table and the fence. Note that the fence is faced with a board, and this board has a cutout the same diameter as the cutter. The board protects both the fence and you. It keeps the cutter from biting into the metal fence, and the cutout surrounds the unused portion of the cutter. Never cut a rabbet with part of the bit or cutter exposed.
