Abstract
A portable chamfer tool includes a housing configured to support a blade to cut a tenon into a workpiece as the housing is rotated about the workpiece. The portable chamfer tool also includes a passage through the housing configured to receive the workpiece and expose the workpiece to at least one blade to form the tenon and sighting holes disposed in the housing to expose a portion of the workpiece as it travels through the passage. The portable chamfer tool includes measuring marker disposed about the sighting holes to indicate a measure of a length of the portion of the workpiece exposed by the sighting holes. The portable chamfer tool provides a means to form a taper on a first end of a peg disposed in a tenon and mortise joint that is substantially matched to a preformed taper on a second end of the peg.
Claims20
A tenon cutter for cutting a shaped surface into an end of a peg, the tenon cutter comprising:
- a housing having an axis, a cutting portion with a receiving face on a first side thereof for receiving the end of the peg to be shaped, and a measuring portion extending from a second side of the cutting portion, the second side being opposite the first side;
- a passage axially extending through the housing from the receiving face of the cutting portion, through the cutting portion, and into the measuring portion;
- at least one mounting surface on the cutting portion of housing, the at least one mounting surface configured for mounting a removable blade;
- at least one removable blade mounted in the at least one mounting surface and having a cutting edge that extends from a first terminal point to a second terminal point in a direction away from the axis, such that, when the housing is rotated about the axis, the cutting edge of the at least one removable blade defines the shaped surface to be cut into the end of the peg;
- at least one sighting hole extending from an outer surface of the measuring portion to the passage;
- and
- at least one measuring marker around the outer surface of the measuring portion of the housing and intersecting the at least one sighting hole.
A portable chamfer tool comprising:
- a housing having a rotational axis;
- a passage through the housing configured to receive a workpiece;
- a blade supported by the housing, at least a portion of the blade extending away from the rotational axis, an edge of the blade defining a tapered surface when rotated with respect to the rotational axis;
- at least one sighting hole disposed in the housing to expose a portion of the workpiece as it travels through the passage;
- and
- at least one measuring marker around the housing and intersecting the at least one sighting hole to indicate a measure of a length of the portion of the workpiece exposed by the at least one sighting hole.
