Flax Brake: a Double-Cleft Hand Brake in Hardwood

The brake breaks the dried woody core of retted flax into fragments and leaves the fibre whole. A hinged hardwood sword drops between thin boards set edgewise in a frame; a double cleft is handier than a single one. The picture: a simple single-cleft brake (Лапоть, CC0).

Legs and base

Cut two plank legs. Mortise one into a heavy hardwood block so the brake stands solid, and join the legs with two stretchers.

Sword

Shape the sword from one piece: two laths that fork over the middle board, a handle at the front. Bevel the lower edges, not sharp. Bore it and the back leg for a wooden pin.

Pin and test

Whittle a hardwood pin and fit the sword. Check that it drops into the gaps without bottoming out; plane the laths if it binds. Lay a dried flax bundle across and strike: roots first, then tips, then the length.
