Primaterra

This chair is built from sweet chesnut sticks, abundant in my locality, in diameters between 4 and 8 cm, joined by tenons and mortises. This means that at the junction between a leg end a stretcher, for example, the leg is drilled at a given diameter (not under 20 mm for sufficient strength) and the ends of the stretcher are shaped to fit using an axe and/or a knife.

When you have a good fit, the end of the tenon is sawn so that a wedge can be inserted. Be careful that the wedge is perpendicular to the grain of the wood in the leg, otherwise it may split when the wedge is forced in.

The seat material is obtained from a chesnut log about 10cm in diameter split so as to get several small boards. These are fixed to the top rungs using wooden pins, no metal is used in my furniture, in fact, even some of my homemade tools are in wood.

The back is built up from a nice branch with a comfortable bend I found near the firewood pile. It is fixed to the back posts with tenons and mortises. Another similar part is located lower down to hold two thin uprights which finish off the backrest, and the chair.
