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.
Claims18
A chisel assembly for cutting mortise perimeter cuts into a substrate, comprising:
- a chisel having a blade for cutting mortise perimeter cuts into the substrate, the chisel including:
- a shoulder;
- a handle extending from a first side of the shoulder;
- and
- a chisel locator feature extending from a second side of the shoulder and parallel to the handle, the chisel locator feature configured for locating the chisel relative to the substrate such that the chisel locator feature maintains the blade on a cutting path along a portion of the substrate,
- wherein:
- the blade includes a first blade portion and a second blade portion substantially orthogonal to each other and spaced apart from the chisel locator feature, and
- the chisel locator feature is offset from an edge of the shoulder.
A method, comprising:
- aligning a chisel locator feature of a chisel relative to a substrate, wherein the chisel includes:
- a blade having a first blade portion and a second blade portion substantially orthogonal to each other and spaced apart from the chisel locator feature;
- a shoulder;
- and
- a handle extending from a first side of the shoulder, wherein the chisel locator feature extends from a second side of the shoulder and parallel to the handle, is configured for locating the chisel relative to the substrate such that the chisel locator feature maintains the blade on a cutting path along a portion of the substrate, and is offset from an edge of the shoulder;
- and
- applying force to the chisel to push the blade into the substrate material and generate a mortise perimeter cut.
A method, comprising:
- aligning a chisel locator feature of a chisel relative to a substrate, wherein the chisel includes a blade having 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;
- inducing interaction between a guide locator feature and the chisel locator feature to removably couple a guide and the chisel, wherein removably coupling the guide and the chisel maintains the first and second portions of a blade on a cutting path along an outer surface of the guide;
- and
- applying force to the chisel to push the blade into the substrate material and generate a mortise perimeter cut.
