Possibly the reason using triple chip grind in a production environment, the saw blade plate will be necessarily thicker to accomodate the carbide tips used. A power feeder is not uncommon under such circumstances.
But once again I still don't like the idea of Sillycone on any wood working machinery. We, in Seattle, used a good grade of carnuba wax on all surfaces and it gets just a bit wet up there, if ya folla?
In a production situation where the ripping is one of the first steps in the process of milling then there is always the chance that further milling will reduce the possiblty of Sillycone on the surfaces to be finished but for home/amateur use I still stand bye my previous opinion and experience.
