Abstract
A mortising kit for hinges, locks, strike plates, and the like can include a guide attachable to a subject to be mortised (e.g., door or door jamb). The kit can include a chisel that interacts with locating features of the guide to ensure proper placement of the chisel. Force applied to the chisel can score or otherwise cut the subject to a desired depth, at which point stops or other features of the guide can limit the chisel from scoring or cutting deeper. Placement of the chisel at opposite ends of the guide allow the full mortise perimeter to be scored or cut. Excess waste material can be removed from between the mortise perimeter, such as through use of the block plane.
Claims17
A guide assembly for use with a chisel for cutting mortise perimeter cuts into a substrate, comprising:
- a guide having an outer perimeter, wherein the guide is positionable on the substrate at a location for installing a hinge, the guide including:
- a surface for placement on the substrate;
- a lip oriented to be placed against a front surface of the substrate to position the guide;
- and
- at least one guide locator feature configured to interact with a chisel locator feature on the chisel to couple the guide and the chisel, wherein coupling the guide and the chisel maintains a blade of the chisel on a cutting path as defined by the outer perimeter of the guide.
A method, comprising:
- positioning a guide on a substrate for installing a hinge, wherein the guide includes:
- an outer perimeter;
- a surface for placement on the substrate;
- and
- at least one guide locator feature configured to interact with a chisel locator feature on a chisel to couple the guide and the chisel;
- orienting a lip of the guide to be placed against a front surface of the substrate;
- coupling the guide and the chisel to maintain a blade of the chisel on a cutting path as defined by the outer perimeter of the guide;
- and
- applying force to the chisel to generate a cut on the cutting path to install the hinge.
