Rabbet Knife

Rabbet Knife Figure 14

A second knife should have a straight slotted arm about eighteen inches long, into which blades of various sizes and forms can be put, and which permits their being adjusted to different points, the bits, four or five in number, varying in size from one-quarter to one and a half inch. The forms of blades may be used as designated by Figs. 15, 16, and 17 respectively.

The ‘double’ or panel router is at best an awkward tool, and it requires much skill on the part of the workman to enable him to cut a smooth groove. The common shape of tire cutter blade is shown by Fig. 18. A better cutter is shown by Fig. 19. This has a cutting spur and a smooth face, which protects the molding from being damaged by the cutter. It is a troublesome tool to grind, but it cuts smooth and works easy.

Router Shapes Figure 18-19

Planes and tools for rounding and finishing moldings are necessary. Some of the most convenient have awkward forms, but they can be handled easily. Planes shaped like Fig. 20 (page 37), may be fitted with faces and cutters to work on any part of the body. Ample provision must be made in all cases for free discharge of chips. Each form should have a convex and straight face, and be in right and left pairs. Beading tools, and others with handles of like form, are necessary for working in places that cannot be reached by the planes. The faces and guards of these should be narrow and rounded so as not to scratch. Concave and convex face planes, smoothing plane form, but with a T iron and an open throat, are convenient tools for cleaning off body parts. Fig. 21 shows one of these planes, also a face view of the same.
