RATE OF FEED

When routing or doing related work in wood and plastics, the best finishes will result if the depth of cut and feed rate are regulated to keep the motor operating at high speed. Feed the router at a moderate rate. Soft materials require a faster feed rate than hard materials.

The router may stall if improperly used or overloaded. Reduce the feed rate to prevent possible damage to the tool. Always be sure the collet chuck is tightened securely before use. Always use router bits with the shortest cutting length necessary to produce the desired cut. This will minimize router bit run- out and chatter.

It may be necessary to make the cut in more than one pass with progressively deeper settings to avoid overloading the motor. If the bit cuts freely and the motor does not slow down, the cutting depth is generally correct.

GUIDING THE ROUTER

The router can be guided through the work in any of several ways. The method you use depends, of course, on the demands of the particular job and on convenience.

For routing operations such as grooving or dadoing, it is often necessary to guide the tool in a line parallel to a straight edge. One method of obtaining a straight cut is to securely clamp a board or other straightedge to the work surface, and guide the edge of the router sub-base along this path (Fig. 14).

PR002 STRAIGHT ROUTER GUIDE

(Included with PR20EVSK & PR20EVSNK,

also available as optional accessory)

The router guide is an optional accessory that will guide the router parallel to a straight edge (Fig. 15).

The router guide is supplied in two part held together with a bolt, wing nut and washer. It also includes a wing screw and washer to fasten the guide to the router.

The guide also features a scale for accurately positioning the edge guide relative to the bit. With the guide installed and adjusted, the router should be fed normally, keeping the guide in contact with the edge of the workpiece at all times.

The router guide can also be positioned directly under the router base for operations where a cut is needed close to or at the edge of the work, such as when rounding off deck planks.
