Claim 12

Dependent Claim 52 words

The method or forming a joint according to claim 6 wherein one of the wooden boards has protrusions with sides substantially perpendicular to the surface of the one wooden board and the other wooden board has protrusions substantially parallel to the surface of the other wooden panel to form a 90° joint.

Claim 13

Dependent Claim 113 words

A template for supporting and guiding a router to cut joint members in panels to form an interlocking joint, the template comprising: a form having one side with curved jigsaw puzzle shaped indents with protrusions between the indents, the protrusions and indents in line to form a jigsaw shape, the protrusions being smaller than the indents by a dimension representing a difference in radius between a router bushing and a router cutter, the router bushing having a larger diameter than the router cutter, the template adapted to permit cutting jigsaw puzzle shaped protrusions and indents in the panels t at are of the same size when the router bushing follows the template side.

Claim 14

Dependent Claim 113 words

A template for supporting and guiding a router to cut joint members in panels to form an interlocking joint, the template comprising: a form having one side with curved jigsaw puzzle shaped indents with protrusions between the indents, the protrusions and indents in line to form a jigsaw shape, the protrusions being smaller than the indents by a dimension representing a difference in radius between a router bushing and a router cutter, the router bushing having a larger diameter than the router cutter, the template adapted to permit cutting jigsaw puzzle shaped protrusions and indents in the panels t at are of the same size when the router bushing follows the template side.

Claim 15

Dependent Claim 45 words

The template according to claim 11 including means to clamp a first panel to the jig at a location offset by a half pitch of the protrusions and indents from a second panel, so that the first panel and second panel when joined are aligned.

Claim 16

Dependent Claim 31 words

The template according to claim 11 including means to clamp a panel to the template so the router cuts the protrusions with sides substantially perpendicular to a surface of the panel.

Claim 17

Dependent Claim 31 words

The template according to claim 11 including means to clamp a panel to the template so the router curs the protrusions with sides substantially parallel to a surface of the panel.

Claim 18

Dependent Claim 91 words

A jig for supporting and guiding a router to cut joint members in work pieces to form an interlocking joint comprising: a plurality of fingers with first fingers each having an S-shaped end interspaced with second fingers each having a reversed S-shaped end to form a plurality of curved jigsaw puzzle shaped protrusions with indents between the protrusions, means to clamp the fingers in line, and guide means to guide a router with a straight sided cutter to follow the curved jigsaw puzzle shaped protrusions and indents formed by the fingers.

Claim 19
