Abstract: A tapered dovetail mortise and tenon joint is formed within typically a post and beam or within two joists which intersect perpendicular to each other. The tapered dovetail shaped mortise portion cavity is shaped to interfit with a dovetail shaped tenon portion. The tenon portion has incorporated therein a plurality of acute angles which permit easy assembly, cause precise alignment and cause forces to be created when components are connected using the joint which forces tend to bring the mated components into very rigid tightly interfitted assembled relationship. The joint, when assembled, is not visible because of the unique configuration of the mortise and tenon portions. A very large load bearing capability of inherent in the joint partly because of the large mating surface incorporated into the side surfaces and the bottom surfaces and also partly becuase the integrity of the chords and the web of the "I-Beam" cross section of the components is not violated.

Abstract: A reconditioned tool comprises a cylindrical insert cut from a damaged tool, such as a hog mill, with a milling face formed on one end and a transverse dovetail tenon cut in the other end. The dovetail tenon engages a transverse dovetail mortise in the end face of a cylindrical holder. A transverse slot in the holder splits the end of the holder into two axially extending end sections each of which includes one-half of the dovetail mortise. A clamping device, such as a bolt, draws the two end sections of the holder together to pull the insert firmly against the end faceof the holder through wedging action of the two halves of the dovetail mortise against the dovetail tenon. A locking pin inserted through aligned transverse grooves in the holder and insert prevents a lateral displacement of the insert relative to the holder.
