I’ve buit a lot with cherry, but I’m having a new problem. I have this dark grain streaks in the woods. It looks a little like what often happens with white oak. I’ve just hand planed this whole board after using 80 grit ROS. It doesn’t seem to want to Go away. Ideas?

Charles it looks like a bacteria or fungus start when when the wood was wet. It’s not a very pleasing looking pic of Cherry. I think most would agree it’s pretty ugly. Maybe it’s bad lighting?
I would also like to offer one suggestion planing after sanding. Some woods will trap the grit that breaks loose from sandpaper in the pores. If you try to plane it by hand or machine you will be cutting the wood with what ever grit you used. Dull knives would be expected
Cherry does have small pores but it’s still bad practice
Plane first sand last.
Good luck and always go with the grain

The lighting is bad. I usually do plane first, but I was dealing with this unexpected issue.

Charles,
This almost looks like iron stain and can be caused by rust from metal and it can go deep

The cure is oxcylic acid, AKA, deck brightener, or Wood bleach at Wal Mart

its not expensive , and while i cant be positive, may be worth a try .

Did the board come like this and you thought you could plane/sand it off or was this after resawing? Just asking out of curiosity, nothing else.

Have your say...
