re: Re-Milling S4S Lumber? Perfection, Spearguns, and Other things

S4S as sold to end consumer is actually very rarely anywhere near S4S done on a jointer, TS, and planer. Yes it is "surfaced" but more often what is also known as skip planed. Because of all the variables that can make it go to Crapsville if/when it sits unused for a period of time. This is my experience in 60 years of using hardwoods anyhow.
