Abstract
The pipe cutter includes a jigsaw with a motor that reciprocates a saw blade back and forth. A way is clamped to the jigsaw. A workpiece holder is slidably mounted on the way. The workpiece holder has a workpiece slot with a base, two side walls and a saw blade slot. A handle is attached to the workpiece holder. A pipe that is to be cut is placed in the workpiece slot and the workpiece holder is moved along the way toward the saw blade. The saw blade forces the pipe toward the base of the workpiece slot and cuts the pipe.
Claims14
A pipe cutter comprising
- a power saw with a reciprocating saw blade;
- a way secured to the saw;
- a workpiece holder slideably mounted on a first side of the way and having a workpiece slot with a base, an open side opposite the base for workpiece ingress and egress, and two sidewalls that are fixed relative to the base and cooperable with the base to position a workpiece, the workpiece holder further having a saw blade slot that intersects the workpiece slot and is generally perpendicular to the workpiece slot, wherein the way extends between the workpiece holder and the saw such that the workpiece holder is disposed on the first side of the way and a substantial portion of the saw is disposed on an opposite second side of the way, wherein the reciprocating saw blade extends through the way from the second side to the first side thereof and is extendable through the saw blade slot, and wherein the reciprocating saw blade moves from the open side of the workpiece slot toward the base of the workpiece slot to initiate cutting;
- and
- a handle attached to the workpiece holder for moving the workpiece holder along the way.

A pipe cutter comprising
- a power saw with a reciprocating saw blade;
- a way rigidly secured to the saw;
- a workpiece holder slideably mounted on a first side of the way and having a workpiece slot with a base, an open side opposite the base, and two sidewalls that are fixed relative to the base and cooperate with the base to position a workpiece, the workpiece holder further having a saw blade slot that intersects the workpiece slot and is generally perpendicular to the workpiece slot, wherein the way extends between the workpiece holder and the saw such that the workpiece holder is disposed on the first side of the way and a substantial portion of the saw is disposed on an opposite second side of the way, wherein the reciprocating saw blade extends through the way from the second side to the first side thereof and is extendable through the saw blade slot;
- a first stop including a first pair of cooperating surfaces carried by the way and the workpiece holder which contact each other to limit movement of the workpiece holder along the way in a first direction;
- a second stop including a second pair of cooperating surfaces carried by the way and the workpiece holder which contact each other to limit movement of the workpiece holder relative to the way in a second direction;
- and
- a handle on the workpiece holder for moving the workpiece holder along the way.
