And on my watch, cherry is even worse than maple, as it can rosin up a sharp saw blade and start burning even at a decent feed rate about 10 minutes worth of cutting after you've "Easy Off'd" the blade with about an half an hours service on it. The best blade I've found I guess I'll have to buy on the net, CMT has one with an ATBF tooth setup, sweetest cutting blade ever. Lowes was carrying it 2 years ago, and I should have stocked up I guess. You can cut an edge with that, and go straight to wiping Sam's Stuff on it, its that smooth.
