==Description==

==Description==

The hand router is very versatile but can also be a very dangerous tool if not used properly. Used in conjunction with the proper jigs and templates, the router can accomplish a wide variety of tasks with relative ease. Holes and channels of varying depths and nearly limitless shapes can be cut. The router can also use special bits to cut bevels and chamfers along the edges of a workpiece.

Each bit is made for a different job. The wood shop has a wide assortment, although less common types may be unavailable. It should be noted that different bit sizes and profiles will operate better at different speeds. The amount of material the is being removed in each pass as well as the hardness of the wood should determine the speed the router is ran at. With reference to straight bits, if the bit is less than 1" in diameter, many recommend speeds near 24,000 rpm. For bits 1" - 2.5", 16,000 to 18,000 rpm, 2.5" to 3", 12,000 to 14,000 rpm, and for bits of more than 3", a common recommendation is 10,000 to 12,000 rpm.

Each bit is made for a different job. The wood shop has a wide assortment, although less common types may be unavailable. It should be noted that different bit sizes and profiles will operate better at different speeds. The amount of material that is being removed in each pass as well as the hardness of the wood should determine the speed the router is ran. You should not attempt to use any bits over 1" in diameter as these are designed for use in a router table and could create a dangerous situation.

Occasionally routing can leave burn marks on the workpiece. This usually means that the bit in the router has become dull, let a shop supervisor know if a bit seems dull. Sometimes the burning is due to build up of resin and other gunk (a technical term) on the back of the blade insulating the bit and allowing for heat to build up, make sure to keep bits clean. A final possible cause of burning wood while routing is taking passes that are too slow or setting the router bit speed too high.

A final possible cause of burning wood while routing is taking passes that are too slow or setting the router bit speed too high. A good rule of thumb for setting router bit speed is the larger the cutter the slower the speed.  Set the spindle speed adjustment to around 20000 RPM when starting out and you can adjust as needed. If a specific cutter is marked with a recommended speed start with that.

10. Only handle the router with both hands on the handles. Move the router onto your material.  Make sure the cutter does NOT make contact.   

10. Only handle the router with both hands on the handles. Move the router onto your material.  Make sure the cutter does NOT make contact.   

11. Turn on the power switch and let the router get up to speed.  Slowly feed the cutter into the material until the bearing makes contact with the material edge. Keep the guide plate flat on your material and slowly feed the router along the edge. If you travel too slow the wood will start to burn. Traveling too fast will produce a poor cut. Be careful to keep the router from tilting when traveling along the edge and especially while traveling around a corner.   

11. Turn on the power switch and let the router get up to speed.  Slowly feed the cutter into the material until the bearing makes contact with the material edge. Keep the guide plate flat on your material and slowly feed the router opposite the direction of the spinning cutter.  If you travel in the wrong direction the cutter will try to pull the router along. If you travel too slow the wood will start to burn. Traveling too fast will produce a poor cut. Be careful to keep the router from tilting when traveling along the edge and especially while traveling around a corner.   

12. Power off the router after making your cut.  Let the spindle stop turning before moving the router away from the work piece.
