I have a fairly new set of carbide teeth in my jointer/planer (I just rotated them maybe a hundred bf ago), but I keep getting tear out on this batch of tiger maple. I ran an earlier batch thru on older, more worn teeth and it came out fine. I've read somewhere that wetting the wood will help minimize that, but I can't remember what was used, how much, how long before planing, etc. And since I have no recollection of where I saw it, I'd rather hear or read it here before I tried it.
