Abstract

Claims (92)

1 . A guide system for woodworking operations using a cutting member having a base plate, the guide system comprising:

a sled configured to slide on a top surface of a workpiece;

the sled having a front member;

the sled having a pair of side members;

wherein the pair of side members are operably connected to the front member;

wherein the sled is configured to facilitate lateral repositioning of one of the pair of side members relative to the other of the pair of side members so as to adjust a distance between the pair of side members;

wherein the pair of side members are configured for side edges of the base plate of the cutting member to be placed on the pair of side members;

wherein the pair of side members are configured to slide on and in contact with the top surface of the workpiece during a cutting operation;

the pair of side members having a set of attachment members configured to engage the base plate of the cutting member so as to facilitate secure attachment of the cutting member to the sled while allowing a blade of the cutting member to reach down and through the workpiece during the cutting operation;

wherein the set of attachment members are laterally adjustable in two dimensions relative to the base plate so as to adjust the lateral positions at which the set of attachment members can be attached to the base plate of the cutting member.

2 . The system of claim 1 , wherein the cutting member is a circular saw.

3 . The system of claim 1 , wherein the cutting member is a jigsaw.

4 . The system of claim 1 , wherein

the front member has a pair of slots;

wherein the pair of side members are operatively connected to the front member through the pair of slots of the front member; and

wherein the pair of side members are configured to move laterally within the pair of slots of the front member.

5 . The system of claim 1 , wherein the set of attachment members includes at least one attachment member;

wherein the at least one attachment member is configured to facilitate secure engagement of the cutting member to at least one of the pair of side members;

wherein the at least one attachment member is movable along a length of the at least one of the pair of side members;

wherein the at least one attachment member is configured to move inward and outward relative to the at least one of the pair of side members; and

wherein the at least one attachment member is configured to pivot about a vertical axis.

6 . The system of claim 1 , wherein each of the pair of side members have a respective one of the set of attachment members;

wherein the respective attachment members of each of the pair of side members are adjustable side-to-side as well as being adjustable forward-to-back.

7 . The system of claim 1 , wherein the pair of side members extend a length from a front end to a back end;

wherein the pair of side members have at least one slot;

wherein the at least one slot of the pair of side members extends a length from near the front end towards the back end of the pair of side members;

wherein the pair of side members have at least one attachment member of the set of attachment members; and

wherein the at least one attachment member is movable along a length of the at least one slot of the pair of side members.

8 . The system of claim 1 , wherein

the pair of side members extend a length from a front end to a back end;

the pair of side members each having a first slot and a second slot;

wherein the first slot extends a length from the front end of the pair of side members to near a midpoint of the pair of side members;

wherein the second slot extends a length from near the midpoint of the pair of side members to near the back end of the pair of side members;

the pair of side members each having a first attachment member and a second attachment member of the set of attachment members;

wherein the first attachment member is movable along a length of the first slot of the pair of side members; and

wherein the second attachment member is movable along a length of the second slot of the pair of side members.

9 . The system of claim 1 further comprising:

a rail;

the rail extending a length between a first end and a second end;

wherein the sled is operatively connected to the rail; and

wherein the sled is configured to move laterally along a length of the rail.

10 . The system of claim 1 further comprising:

a rail;

the rail having indicia;

wherein the indicia of the rail indicates a distance from an end of a workpiece;

wherein the sled is operatively connected to the rail; and

wherein the sled is configured to move laterally along a length of the rail.

11 . The system of claim 1 further comprising:

a rail;

the rail having a feature;

wherein the sled is operatively connected to the feature of the rail; and

wherein the sled is configured to move laterally along a length of the rail.

12 . The system of claim 1 further comprising:

a rail;

the rail extending a length between a first end and a second end;

the front member having a pair of slots;

wherein the pair of side members are operatively connected to the front member through the pair of slots;

wherein the pair of side members are configured to move laterally within the pair of slots of the front member; and

wherein the front member is configured to operatively connect to the rail and move laterally along a length of the rail.

13 . The system of claim 1 further comprising:

a guide arm;

the guide arm configured to be positioned adjacent an end of a workpiece;

a rail;

the rail operatively connected to the guide arm;

the rail having a length extending from a first end to a second end;

wherein the first end of the rail is operatively connected to the guide arm; and

wherein the sled moves along a length of the rail.

14 . The system of claim 1 , wherein the sled is configured to be slid on and in contact with the top surface of the workpiece when performing the cutting operation to cut the workpiece using the cutting member;

wherein the set of attachment members hold the base plate in a stationary position relative to the sled during a cutting operation.

15 . A guide system for woodworking operations using a cutting member having a base plate, the guide system comprising:

a sled configured to slide on and in contact with a top surface of a workpiece when performing a cutting operation to cut the workpiece using the cutting member;

the sled having a pair of side members;

the pair of side members having a set of attachment members configured to engage the base plate of the cutting member so as to facilitate secure attachment of the cutting member to the sled while allowing a blade of the cutting member to reach down and through the workpiece;

wherein a bottom side of the pair of side members is configured to contact the top surface of the workpiece in one or more contact areas;

wherein the one or more contact areas includes a first contact area extending beyond a left side of the base plate and-includes a second contact area extending beyond a right side of the base plate, thereby providing a stable base for the sled and cutting member on the workpiece when performing the cutting operation;
