a friend of mine showed me this piece yesterday. it is local black walnut (NW indiana). he said that he had a couple of boards like this. this is just one small end cutoff that he carries around. this pattern is in the endgrain, and ran through the entire length of the boards. it looks like gear teeth and is very clear on the actual piece. my first thought was that it was somehow caused by a chainsaw blade when the tree was cut down. but he said that not matter where in the board he cross cut it, it was there, not just the original end cut. any ideas what causes this?

probably something or things leaning against the tree that it grew around.

Pretty bizarre. I’d have to agree with Bob,though.

That’s Dovetail Walnut…. Very rare. Used for making dovetails.

if a chain or broad tooth saw was cought in the base of the tree, the rust could be carried up through the grain with moisture moving up the tree. I’ve seen rusty from nails form straignt lines a couple feet long. I would expect the pattern to blur more as it moves further from the source, but I guess that would depend on the grain pattern of wood. I’ve never seen anything quite like it, but this is the best expaination I can come up with.

Thats pretty bizarre. I wonder if someone put a gear around the tree when is was very small, then the tree grew up around the gear and it caused some kind of pattern in the growth of the tree all the way up the trunk ??!!

I’m trying to think of some smart a** comment to make, but I can’t beat the dovetail walnut comment above.

Looks like the tree was brought down with a harvesting machine, essentially a big Cat track-hoe with a large blade and grapple instead of a bucket, lots of em’ used to clear railroad right of ways for clearance.

That is not Indiana wood. It came from area 51, and is being recalled because of secret code dating errors.

I wonder if it grew up through some sort of ring. Maybe someone dropped it around the base of the tree when it was just a shoot and it grew up around it.. Rust carried up through the wood? Is the pattern centered on the pith?
