I believe that crack was there when you bought the wood. Because I live in so cal also and have bought white oak many times from different places and never had it crack across the grain like that,
What you can salvage is your call there’s no way to tell from a picture what good or bad.
Good Luck

I’ve had red oak do this, but I don’t have any that is QS to compare it with. I believe the piece I have left is rift sawn. I’ll try to remember to dig it out to see. That’ll be tomorrow at the earliest, but I’m going to the gun range and a wrecking yard tomorrow for the deals, so it may be later than that. I’m also in so Cal, where the relative humidity doesn’t change all that much.

I see it quite a bit in both red and white oak. Sometimes it won’t look bad until you start milling and it will go at an angle across several inches. There will also frequently be darker areas around it which seem to indicate that it grew that way. If you look at the ends of logs, you’ll see cracks like that sometimes.

Thanks for the info, guys! I guess the big take away for me is that I’m happy it didn’t happen in the project after I incorporated the wood into it. Time to go out and get some more QSRO.

It is probable that the wood was dried a bit too fast. If oak is dried too fast, some of the wood fibers will fail internally due to the stress of the drier shell trying to shrink but the too wet core won’t let it. That stress is relieved by internal checking. I have dried thousands of bf of oak in my kiln, and so far, I have only messed up one load. I assumed the moisture content was low enough going in for the settings that I was running the kiln under, but I was wrong. Dried it too fast and many of the 2” thick boards honeycombed.

I’ve seen that before in both red and white oak. I wouldn’t say that it is common but it is also not unusual. The cracks can be fixed if they are not all of the way through the board. In the first pic, you can inject a little bit of glue under the edge of the crack and then clamp it. Liquid hide glue is better than alaphatic resin glue for this as it is more compatible with most finishes. Sand it out and it will be invisible. Similarly in the second pic put some glue in the crack and then sand it to add dust to the filler, should be nearly invisible. If you carefully lay out your project so that both of these defects are on a less visible part of the project, like the inside of a cabinet or the back side of a drawer front, you won’t have to waste the wood.

I’m with Bondo as to the fix.

When this happens to me (I seem to find a similar problem in every 100bf, I buy), I;ll either cut around it if possible or snap the part along the crack and reglue it.

that top pic looks like one caused during felling of the tree.

Back in 2011, a series of tornadoes swept through the County where I live and uprooted thousands of large old hardwoods. Much of this wood was turned into lumber from the many band saw mills in the area. A lot of this lumber had defects like your pictures because the trees were twisted in very unnatural ways. I have been working with red and white oak for about 40 years and that is the first time i saw such damage.

Yeah, when you back off from the board, you can see a lot of twist in the main crack. Wouldn’t surprise me at all if this was tornado shake. Kind of makes me want to do something interesting with it…

That crack goes across the grain it’s not fixable. Don’t listen to those guys steering you wrong.
Looks like it was caused from falling the tree.
Just drive down to peterman lumber and buy a new board.

Peterman Lumber, interesting. I’ve been going to Austin Hardwoods and Strata Forest Products. Is Peterman worth the drive?

Like the guys said that’s not an unusual defect in oak. When I was grading staves at my grandpa’s sawmill I used to catch a few of these defects every day. Oak likes to split if it gets smacked funny on the end grain.

No Peterman lumber isn’t worth the drive. They do have have a good selection of veneer core plywood’s. But we won’t go there. :)
Austin Hardwoods in Santa Ana is just as good maybe a little bit more expensive.

OK, Peterman is the right option. I called Austin Hardwoods in Santa Ana—they don’t have QSRO and can’t order it (unless I want about a thousand board feet). Strata? Nope. Orange Coast? Nada. Bohnhoff and Saroyan in LA? Goose egg.

Peterman had it for $4.84 a board foot and had a nice selection (though, I had to hunt for boards 8” wide or wider). Got what I need and my project is back on track. I’ll definitely be back.

A little late to the party, but that isn’t all that unusual. I don’t use much red oak, but I do use a lot of white oak, and have seen that a number of times.
