Abstract
An asymmetrical corner joint in a material having a planar surface, in which one side of the joint is shaped to be a slanted plane and the other side of the joint is shaped to be a beveled plane and a shoulder plane, such that when the joint is formed the slanted plane and beveled plane abut and the shoulder plane abuts a portion of the planar surface adjacent the slanted plane. A tool set for use with a router for shaping the two sides of the asymmetrical corner joint in one pass, the tool set including a bit with an angle cutting portion and a shoulder cutting portion, and a canting base for use with the router for tilting the angle of rotation of the bit such that the angle cutting portion cuts both sides of the cut and the shoulder cutting portion only cuts one side.
Claims15
An asymmetrical corner joint between:
- a first piece of work material and a second piece of work material both having the same material thickness, wherein:
- the first piece of work material has an outer side, an inner side and a first joint end comprising a slant plane extending between the outer side and the inner side, wherein a band of the inner side adjacent the slant plane is planar;
- and
- the second piece of work material has a second joint end comprising a beveled plane and a shoulder plane,
- wherein, with the first piece and second piece in position to form the corner joint:
- the beveled plane is adjacent to, and in parallel alignment with, the slant plane;
- and
- the shoulder plane is adjacent to, and in parallel alignment with, the planar band of the inner side.
