s4s = surfaced on 4 sidesNice build! What's a S4S and a "bullnose"?
Bullnose + The rounded corner on finished lumber. It keeps splintering at the corners to a minimum.
My first fifteen years of working were in a crossarm mill and those term were common. Before you ask, crossarms are the predrilled and treated wood cross members on utility poles.
