The words construction and clear pine may not be the correct terminology. This week end I cut a couple of things. One was a tractor I had started a couple of months ago and quit. I quit because the grain pattern was so pronounced that the blade would cut a few strokes and then grind away for a bit and then start cutting again. It was a pain. It was what I call construction grade or cheap stuff. I then cut a Steve Good word pattern in what I call clear pine. It cut so silky smooth, almost like Poplar. The grain nearly invisible. I cut pine because it is fairly inexpensive and readily available. There two HD and Lowes near my home. Perhaps I'm the only scroller that did not know about the extreme differences. I was amazed.
