Will plywood be replaced by OSB (Oriented Strand Board)?
In the early 80's some industry leaders thought the days of softwood plywood
were coming to an end, to be replaced by waferboard and OSB. But new technology
has allowed the use of smaller logs (as small as 5 inches in diameter) to remain

How small of a log can be peeled?
New lathe technology allow logs as small as 5 inches in diameter to
be peeled. And, spindleless lathes can peel down to a 2-inch core.
How important is the quality of logs coming to the veneer plant?
of a log entering the plywood mill is important for two
reasons: it determines the quality and yield of veneer and
because "bad" logs those that split on the
lathe because of heart rot or other reasons, can seriously
reduce the production rate of the mill.
Because of the high cost of top grades of lumber, those logs with the fewest
knots and other defects go to the sawmill, rather than the veneer plant. Sheathing
grades of plywood can be produced from logs of intermediate quality. However,
plywood plants producing the high grade sanded plywood grades still need
the best logs available.
