Wood crafter is the skill associated with the woodcrafting labor. Woodcrafters make wooden crafts, bolts, nest boxes, jugs, pots and hives at a craftsdwarf's workshop. Some instrument and instrument parts may require wood crafting, depending on the particular world. As with other crafting skills, higher skill means faster performance and higher item quality.
Because wood has a low material value, and is very useful for other purposes, a woodcrafter is somewhat less useful than a stonecrafter or bone carver. However, if wood is plentiful, then wooden bolts can be a useful supplement to bone for training purposes. Wooden pots are nearly identical to wooden barrels, so you could have your woodcrafter make them while your carpenter makes other things.
