I have some cherry lumber that can hardly be classified as Select. It is full of splits, checks, warps, knots, and wavy grain. It has been cut and stored for several years and is quite dry, around 8% by my calculation (oven test). I’ve been working with it to cut out the best I can find for a current project. Aesthetically, I can work with the wavy grain, knots, etc. and use it to benefit the project. My question is what to look for that may cause structural problems. For example, it is not uncommon to find hairline cracks in the middle of otherwise nice boards. These cracks are so fine that you need magnification to make sure they are cracks. They don’t usually go all the way through. What kind of problems can I expect with these, if any. Also, I have found some boards with some interesting streaking (see photo) that looks somewhat like spaulting. But, I don’t think it is. I think these boards are very special and would love to use them for visual effect. But, again, I’m not sure about possible structural problems. Has anyone had any experience with this? Or, can you point me to any articles on the subject?
Thanks

olddusty,
Thanks for the encouraging words. i'm hoping to find some more of the pitchy grain as I go through the pile. It is quite striking.
If I know I'm dealing with a board with hireline cracks, is there anything to do to prevent problems with the finish? Does one tyype of finish work better with this than another? Does it do any good to use a filler or sealer first? Or, is it best to just rip the board at the crack and glue it back together? Other than structural problems, do the hairline cracks get worse after the piece is finished?

If you are talking about hairline cracks that do not go deep or through at all then I would do nothing , filling may make the color change that makes them stand out more then going away.
In Maple the cracks do not get larger and they were faily microscopic or very smallish and no structural integrity was compromised by the cracks I have seen , not sure about yours .

oldusty,
Yes. These cracks are very small. You need a magnifying glass to make sure they are a crack and not just some darker grain. They don't appear to go all the way through. However, they can be an inch or more long. I'll not plan on doing anything special about them except, maybe, pray a little. Thanks for the feedback.

let us know if the praying helps .

Thanks for the help
I love gummy cherry for most projects. It's character !!
you mean Cherry gum , right ?
Almost gum
Actually, candy was like frog hair when I was a kid. We used to chew on Sassafras leaves, Wintergreen leaves and berries, Mint leaves, Berries in season, Fruits in season, Sour grape vine "snake tongues" Hickory, walnut & butternuts, watercress, Stinky ramps, wild ginger root. And yes!! Black Cherry Gum ;-) Yule Gibbons was a hero of mine. Even used crushed touch-me-not juice to soothe poison ivy and mosquito bites.
Gotta love being a country boy and still do.
My guess for the two boards shown are that the surfaces were near the bark, and the darker "lines" are missing wood there the annual growth rings curve into or out of the face of the board. If memory serves, as I haven't seen it in quite a while, it was on boards from a standing dead tree that had started to rot a bit - the wood had started to soften. If you can dent the wood as easily as say poplar with a fingernail the wood may be a bit soft. As mentioned, dark lines and irregular small spots are often called pitch or resin pockets. Some people consider these defects, others don't. Some say po-tay-to, some say po-tah-to.
The two boards
I haven't planed these boards yet. But, they seem quite solid, are straighter, contain fewer splits than most of the pile, and contain very little sapwood. My current project is a chest of drawers. I've found enough of these boards for the drawer fronts. I've got my fingers crossed hoping they will look as good as I imagine.
