Peg (page 63) Secures the slats in the post mortises. Like the wedges, the pegs are made of a contrasting hardwood for visual appeal |
|
Slat mortise (page 61) Pouted with mortising hit while post is still square |
|
Slat (page 63) Usually spaced an equal distance from adjoining slats. The curve should fit comfortably against the back of the person who will use the chair |
|
Seat (page 54) Usually 1A to 2 inches thick; made of kiln – dried, edge-glued boards and cut to size. Various hand and power tools can be used to shape the seat to conform to human form. Green wood can also be used; it is easier to shape than kiln-dried wood |
|
Kerfed tenon (page 56) Cuts are made with back – saw or band saw to accept wood wedges; in green wood assembly, a chisel can be used to split the tenon after it is installed in the mortise |
|
Side stretcher Measured when legs are in place and cut to size before turning |
|
Wedge (page 53) Contrasting hardwood wedge secures the leg tightly in the mortise |
|
Leg (page 56) |
|
Front stretcher (page 56) Installed higher than side stretcher to discourage its use as a foot rest, which can lead to breakage; stretchers serve to provide proper tension to the leg assembly |
|
Sack stretcher Measured when legs are in place and cut to size before turning |

Making and using a cutting list
A cutting list records the finished sizes of the wood needed for a project. If you buy plans, a list may be included; otherwise you will have to make your own based on a drawing of the design. Lumber is often sold in board feet. As explained on page 16, 1 board foot is equivalent to a piece of wood 1 inch thick, 12 inches wide, and 12 inches long. Once you have tallied up the number of board feet for all the pieces, you

would normally add an extra 20 to 30 percent to account for defects in the wood and waste. Add at least 50 percent for chairs, however, as there is inevitably more waste because the appearance of each element is of critical importance. For the chair project shown in this chapter, which totals roughly 5 board feet, you should order at least 8 board feet and you could quite easily use 10.
