The wood must first be cut to approximate length, and it is always better to square off from either a sawn edge or a pencil-line along the length if the planks are waney. If an incorrect line is drawn—and all measurements should always be checked and double checked—then it should be cancelled out and a broad arrow-drawn against the corrected measurement (128A). The ends of the plank should be care-
fully examined for hidden splits and the first few inches of any plank which has been stored for any length of time may have to be sacrificed. Due allowance for working must be made, with 1/4 in (6 mm) on width and 1/2 in (12 mm) on the length for the first rough sawing to dimension unless the cuts are machine-made and accurate. Customary allowance for planing (surfacing) sawn thicknesses is usually 3/32 in (2.5 mm) for each wrot (finished) face.
The following is an outline of procedure using predominantly hand tools. Although many of these operations would normally be undertaken with the aid of machinery in professional shops, at some time or other, particularly on one-off, prototype or site work, every one of these hand processes might be used. Also, there is no better way of understanding the materials we work with than through a basic training in hand skills and techniques.
