There are lots of Pine woods in North America as well as the rest of the world. We stock and use two Pines, Ponderosa (Yellow) Pine for clear panel because the logs are large enough to get clear veneer and lumber from but the knots are too big for veneer production. White Pine for knotty because the knots are small enough to stay together when sliced. Lodgepole pine finds its way into both productions from time to time as does Sugar Pine. Once in a while we will get in some Eastern White Pine which yields clear and knotty in both veneer and lumber. Pine isn't to bad to work with, although, knots on an edge that is to be spliced, will usually draw back and or crack if heated. Handling Pine, Spruce, Fir, Redwood and Cedar can be frustrating because they all scratch and dent easily.
