[2] The types of wood warping include: bow: a warp along the length of the face of the wood; crook: a warp along the length of the edge of the wood; kink: a localized crook, often due to a knot
Lumber, pulpwood, shingle bolts, and whole logs move at different speeds and were prone to double-up in a V-flume’s low grades and curves. Finally, box flumes could move an unprecedented amount of material, up to a maximum capacity of 300,000 board feet (710 m 3 ), or three times as great as the maximum for a V-flume.
