Last year i was given a black walnut tree that fell in a storm...so I cut it and hauled it to my local saw mill... now its milling time...

This weekend I milled up some of the narrow stock and was pleased to find some pretty cool grain patterns.





After jointing, I ran it through the planer (just put new blades in my planer)
but I am getting some tear out regardless of how fine a pass i take.
Any suggestions to avoid / correct or process this?

Looks like the grain is flowing in two directions in the board on the photo,
so tearout is almost inevitable.
If you can, try passing the board skewed in the planer (usually helps.)

The last two board shown are pretty much guaranteed to have grain running more than one direction. And the closer you get to that knot (looks like there was a pretty big branch there), the worse the situation will become.

Did you have them lumber the wood above the first major branch?

For power jointing and planing, you are likely to always get a little bit of tearout with this wood. Spiral heads help, sharp heads help, well adjusted machines help, VERY light passes help. A quick wipe with some mineral spirits might soften things but go easy on the stuff around the machines. But in the end you will probably need to resort to a high angle plane (>50 degree effective cutting angle + light cuts), cabinet scraper (i.e. Stanley 80), scraper plane (i.e. Stanley 12 or 112), card scrapers, creative sanding or some combination of all of the above. If you can get time on a drum sander, that might help but those can be fussy machines and would just as soon put a nifty burn mark across your workpiece as look at you.

Good luck, the walnut looks like it has some great figure, suitable for accent pieces but it will make you fight for every square inch of surface!
