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 mortising kit, comprising:
- a chisel having a blade for cutting mortise perimeter cuts into a substrate, the chisel including a chisel locator feature, the blade including a first blade portion and a second blade portion, wherein the first blade portion and the second blade portion are substantially orthogonal to each other and spaced apart from the chisel locator feature;
- and
- a guide having an outer perimeter, wherein the guide is positionable on the substrate at a location for installing a hinge, the guide having at least one guide locator feature for interacting with the chisel locator feature to removably couple the guide and the chisel, wherein removably coupling the guide and the chisel maintains the blade of the chisel on a first cutting path around at least a first portion of the outer perimeter of the guide.
A mortising kit, comprising:
- a chisel having a blade for cutting mortise perimeter cuts into a substrate, the chisel including a chisel locator feature, the blade including a first blade portion and a second blade portion, wherein the first blade portion and the second blade portion are substantially orthogonal to each other and spaced apart from the chisel locator feature;
- and
- a guide having an outer perimeter, wherein the guide is positionable on the substrate at a location for installing a hinge, the guide having first and second guide locator features for interacting with the chisel locator feature to removably couple the guide and the chisel, wherein removably coupling the guide and the chisel via the first guide locator feature maintains the blade of the chisel on a first cutting path around at least a first portion of the outer perimeter of the guide and removably coupling the guide and the chisel via the second guide locator feature maintains the blade of the chisel on a second cutting path around at least a second portion of the outer perimeter of the guide, and wherein the first and second cutting paths partially intersect to form a mortise perimeter.
A method, comprising:
- positioning a guide on a substrate at a location for installing a hinge, the guide including a guide locator feature;
- aligning a chisel locator feature of a chisel with the guide locator feature of the guide;
- inducing interaction between the guide locator feature and the chisel locator feature to removably couple the guide and the chisel, wherein removably coupling the guide and the chisel places first and second portions of a blade of the chisel against an outer surface of the guide and a surface of the substrate, the first and second portions of the blade being substantially orthogonal to each other and spaced apart from the chisel locator feature;
- and
- applying force to the chisel to push the blade into the substrate material and generate a mortise perimeter cut.
