When planing S2S lumber, I usually look for the grain slope to avoid tearout. On flat sawn oak this is pretty easy to see. Lately I have been planing some quarter sawn red oak that has heavy flecks like QSWO. You really cannot see the grain direction on this stock. But you can feel it. I found that the lumber is like fish scales – smooth when you feel it in one direction, and rough the other direction. If I take the time to orient the board so it would feel smooth to my hand as it passes under the planer head, I can virtually eliminate any tearout. I use a Dewalt 735 on the 7350 planer stand.
I would also be interested in any custom planer support tables that people have built.
