Lower diameter limit = smallest top diameter allowed for logs within this sawing pattern. Upper diameter limit = largest top diameter allowed for sawing pattern. Width = nominal width of centerboards (main yield). Thickness = nominal thickness of centerboards. Sideboards were edged to various sizes depending on value
