The invention relates to an assembly comprising two jigs which can be used to produce a dovetail mortise and tenon in order to assemble members of a frame. This present invention concerns a device or arrangement, an assembly or a kit, that includes jigs employed for the execution of dovetail mortise and tenon joints, intended for assembling the parts of timber beams. In the area of roof timbers, the assemblies usually employed consist of straight mortise and tenon joints.
The implementation of a straight tenon joint is problematic in that it is necessary to use either a high-cost, stationary roof-timber tenoning machine, or a portable circular saw necessitating several manual operations and where the final result lacks precision. Straight mortise and tenon elements executed on roof timber components are slotted into each other by presenting the end of the roof-timber component equipped with the straight tenon against the face of the other part equipped with the mortise, in the same plane.
This slotting together necessitates the separation of the two roof timber components, by at least the value of the length of the straight tenon, so that the latter can slot into the mortise. Moreover, a straight tenon is able to pull out of the mortise if the assembly is not pinned or held by some other technical means.
This type of joint is also known as pin-and-cove or half moon. This type of joint is very strong and can be constructed with the use of machinery which means production on a mass scale was possible in a factory setting. The Knapp joint, patented by Charles Knapp of Waterloo, WI in , was a huge advance for the furniture industry because it could be made quickly by machines called routers, which could create circular cuts in wood.

Skilled carpenters of old were able to craft beautiful structures and objects all by hand. Many of these carpenters were skilled enough to even be able to create works of art without the need for nails, wedges or bindings.
As we entered the industrial age, we transitioned away from hand crafted carpentry, to more mass produced machine based manufacturing. While this means that we may have lost many of the skills of old, it does make it easier to identify the potential era a piece of carpentry was made in. Simply by looking at the quality of the cuts and the techniques used to assemble the piece, to the style of joinery and the materials used to hold parts together.
