An angle measuring gauge incorporates four arms pivotally connected to form a quadrilateral. The arms are connected to a guide bar that attaches to the quadrilateral along a diagonal and forms an axis of symmetry. A first corner of the quadrilateral is pivotally attached to the guide bar and the opposite corner of the quadrilateral is pivotally connected and is slidable along the guide bar to adjust the angles of the quadrilateral. In practice, the first corner of the quadrilateral is adjusted to conform to a desired angle, and the guide bar bisects the angle formed by the first corner and can be used to either ride in a miter slot of a cutting tool, or adjust a miter gauge of a cutting tool to cut accurate miters.

An adjustable miter gauge for use with a table saw includes a miter attachment and an adjustable guide bar coupled to the miter attachment. The miter attachment rests on a working surface of the table saw. The guide bar is received in a slot in the working surface. The guide bar includes a main body, which has first and second surfaces parallel to side walls of the slot, an adjustable body, which has a third surface parallel to the first surface, and a deformable biasing member. The adjustable body is coupled to the main body and slidable between a first position, wherein the second and third edge surfaces are coplanar, and a second position, wherein the second and third edge surfaces are not coplanar. The biasing member is arranged between the main body and the adjustable body and biases the adjustable body toward the second position.

A mitre cutting guide tool (1) comprises a first body section (2a) having a substantially planar outer face with an outer edge configured to rest against the face of a skirting board or coving to guide a cutting tool in use; a second body section (2b) rotationally connected to the first body section (2a) via a connecting means (5); a sensing means (9) configured to measure the angle between the first and second body sections (2a, 2b); a locking means (5) configured to connect the first and second body sections (2a, 2b) so that the angle can be altered and to lock the first and second body sections (2a, 2b) in position to set a given angle; the second body section (2b) supporting the first body section (2a) at the set angle against the length of skirting board or coving; the connecting means and/or locking means (5) configured so that the space between the first and second body sections (2a, 2b) is substantially unobstructed.

A device for carrying out miter cuts includes two limbs which are secured to a central element in a pivotal manner in each case and so as to be fixable in pivoted positions. Each limb has a stop strip with a contact surface, wherein the contact surface lies opposite a counter contact surface formed by a counter stop. The distance between the contact surface and the counter contact surface can be adjusted by an adjusting element. Furthermore, the limbs and the central element are made of plastic, and a region of the central element from which the guide elements originate and which extends at least over the region between the guide elements has either a metal plate or an exchangeable sacrificial plate.

An angle divider includes a body portion with a proximate end and a distal end. A distal end pivot point is positioned in the distal end of the body portion. A fixed arm and a removable arm are pivotally mounted to the distal end pivot point. The arms and pivot with respect to the distal end pivot point. An adjustable pivot is mounted for sliding movement within an elongated slot formed in the body portion. Brackets interconnect the arms to the adjustable pivot. Movement of the arms results in movement of the adjustable pivot longitudinally along the body portion. A lock 26 locks the adjustable pivot with respect to the body portion, which locks the arms in place with respect to the body portion. The removable arm can be removed from the distal end pivot point and the adjustable pivot point to split the angle.

A portable saw table apparatus for cutting oversized substrates at a work site which provides a centrally pivoted cutting table, the cutting surface of which is not interrupted by a central pivot element; and further comprises a saw support which is also not centrally mounted on the pivoting table. Also provided is a method for cutting oversized substrates such as commercial-sized trim or other construction materials onsite at a construction site.

In a general aspect, a construction tool can include a template portion arranged in a first plane. The template portion can include a rectangular plate having a slot defined, the slot being angled with respect to an edge of the plate and configured to facilitate marking a cut line on a construction material. The construction tool can also include a base portion arranged in a second plane, the second plane being orthogonal to the first plane. The base portion can include a first portion disposed on a first side of the plate, and a second portion disposed on a second side of the plate of the template portion that is opposite the first side of the plate. The first portion of the base portion can have a first thickness, and the second portion of the base portion having a second thickness that is different than the first thickness.
