Re-position the depth control handle for each additional pass until the final depth-of-cut is attained. Once you’ve completed your final pass, loosen the Depth Control Handle, raise the motor, retighten the Handle and turn off the motor. Only when the motor has stopped completely should you re- move and inspect your workpiece.

The quality of your cut will depend on three factors: (1) The depth-of-cut, (2) Your feed rate and (3) The condition of your Router Bit. Shallow cuts, a slow feed rate and a sharp Bit will always produce the best quality cut.

AN IMPORTANT NOTE ABOUT ROUTER MOTOR SPEEDS

Router motors operate at the highest speeds of any woodworking tools. For this reason, unsightly burn marks can often appear where the Bit meets the wood. This is espe- cially true with hard woods such as maple, cherry, oak, etc. which are best worked at slower speeds.

Here are three valuable tips for avoiding burn marks:

1.Always use sharp, clean bits.

2.Never attempt to make deep cuts in a single pass. Taking multiple light passes will always produce better results. For best results, make the depth-of-cut on your final pass 1/16" or less.

3.Always work in a continuous motion without dwelling and don’t forget to raise the rotating bit from the workpiece before turning the motor off.

4.If your Router is a single speed model, consider purchasing a plug-in after-

If you’re planning to make a large quantity of the same product, the fixture duplicating method is best for speed and accuracy – and making your own fixtures to cut out and shape these products is easier than you might think.

Fixtures are usually made from plastic lami- nate-covered materials such as countertop cut-outs for sinks. That’s because these ma- terials will hold up under continuous use much better than ordinary wood. Sink cut- outs are readily available at plumbing sup- ply houses, from contractors, at cabinet shops, or even at many home centers or hardware stores...and are usually very inex- pensive.

TYPES OF FIXTURES

There are three basic types of fixtures for pin routing:

1.Screw-down fixtures . . . are the easiest fixtures to make, but require more time to attach and remove your workpieces than clamp-in or profile fixtures With this type of fixture, screws (or nails) are used to hold your workpiece to the fix- ture.

When building a screw-down fixture, be sure to position the screw holes so your router bit will not cut into the screws once the workpiece is attached. The ex-
