I spent last weekend planing down some 12" wide knotty pine boards with my DW764. I could barely take 1/16" off at a time without popping the breaker. Sure, I could have flipped the knives but there was no way I was going to waste the fresh edge on knotty boards. Perhaps I should have because I ended up melting the drive belt. That stupid belt is $32 and it is on back order! This is that odd instance where I kind of wish the belt were a lot more expensive and/or no longer made so I could justify getting a better planer with a spiral head.
