Title:	The chipping headrig: A major invention of the 20th century
Author(s):	Koch, P.
Date:	1973
Source:	Forests and People 23(2):18-20, 36-37
Description:	A square peg won't fit in a round hole but a square timber can be chipped out of a round log. It's simple, fast and efficient, with a chipping headrig. Virtually every significant southern pine sawmill uses one of these amazing machines, busily making useful most of the wood in the tree, chipping some for paper and uncovering sawtimber where before there was only pulpwood. In short, it has chipped its own little niche in the hearts of southern timbermen.
