Not all of the cutting force is downward. The chain at back side of the bar is pushing upward. It's one thing to be holding the chainsaw as the back side contacts the wood. But I imagine it's different when a board you're holding onto exits a chainsaw.Okay, call me crazy, but why doesn't anybody sell something similar with a finer cut and thinner kerf, as a hybrid between the table saw and the band saw? The blade is well supported, like a table saw, but all the cutting force is directed downward, like a band saw. It strikes me as the best of both worlds when it comes to straight rips and crosscuts; stable and safe.
