After debarking, a log is sawn to required lengths and required cross-sectional sizes. Sawing renders lumber members rough to touch, which can hurt a carpenter's hands. Therefore, the sawn lumber is subsequently surfaced smooth with planing machines. Is surfacing done after the seasoning of lumber or before? Give reason for your answer.
What will be an ideal response?
Surfacing is done after seasoning because lumber must be sufficiently dry for surfacing.
