Mallet Head Angle

Explains how to build a wooden joiner’s mallet from common scraps, covering layout, tenon and mortise cutting, wedging, shaping and face preparation. Preferred woods (hickory handle, Osage or interlocked-grain head like beech) are noted, though the builder used white oak and walnut. Practical techniques include scribing tenon shoulders, cutting cheeks with a rip saw and shoulders with a Ryoba, drilling a stop hole before sawing the wedge slot to prevent splitting, removing most mortise waste with an undersized Forstner bit, squaring the mortise with a chisel, and flaring the mortise toward the striking faces so the wedge locks securely. Clamping the head to the bench while chopping and saving off-cuts for glued leather faces are highlighted; a strong warning: do not drive the wedge until final fitting.

Addresses the core question - what angle to put on the mallet head - by grounding it in the geometry of the mallet’s arc. The face should be cut so it is normal to the chisel handle at impact, preventing twist and deflection. The recommended, user-specific method uses a length of string taped from the chosen pivot (wrist for light taps, elbow for heavier blows) to the top corner of the head, marking where the string crosses the head’s lower edge, transferring that angle with a bevel gauge, then cutting the faces accordingly.
