PILOT TIPPED AND BEARING GUIDE BITS The lower portion of a pilot tipped bit, as shown in (Fig. 17), is a shaft with no cutting edges. Bearing guide bits have a ball bearing to pilot the bit.

This pilot slides along the edge of the work as the rotating blades make the cut, forming molding or decorative edges. The edge on which the pilot slides should be perfectly smooth since any irregularities are transferred to the shaped surface.

TEMPLATES

Using template patterns lets you duplicate designs or letters uniformly time after time. This technique requires the use of an template guide adapter and a template guide.

TEMPLATE GUIDES

(Not included, available as accessory)

The template guide shown in (Fig. 18), is essentially a plate with a collar which is inserted through the hole in sub-base and template guide adapter from below and fastened with a knurled retaining nut. The template guide rides along the edge of the templat while the router bit, protruding below, cuts into the work.

Do not use a bit that may touch the inside of the collar. Select a bit that is about 1/16" less in diameter than the template guide adapter opening.

Template guides are used with a number of special accessories, such as hinge templates. In addition, special templates are easily prepared for cutting repeated patterns, special designs, inlays, and other applications. A template pattern may be made of plywood, hardboard, metal or even plastic, and the design can be cut with a router, jigsaw, or other suitable cutting tool.

Remember that the pattern will have to be made to compensate for the distance between the router bit and the template guide (the “offset”), as the final workpiece will differ in size from the template pattern by that amount, due to the bit position (Fig. 19).
