Dean I see the hin bark in the OP's picture, and yes Birch has the thin (Paper like) peeling bark, as for the lines on the bark, they are not always there, it is very variable from tree to tree.Leo,
My first thought was paper birch, as well, but I decided the peeling bark didn't look quite right. On birch, it's generally very thin and on the OP's picture, it's fairly thick. With birch, if you get a thicker bark peeling, the underside is creamy or tan, and while this stuff has some buff coloring on the peeling bark, it doesn't quite have the right look. And most importantly, on birch there are many, many short horizontal marks on the bark, and the OP's picture shows nearly none.
I have never seen that Marvin, mind you a tree that has been in a bad storm could get wind-shake, and I don't believe that it grows back together.If it is sycamore, stay away from the pith. I've had several rings close to the pith suddenly turn loose, even 1" to 1 1/2" away.
I doubt it is just Sycamore. I have seen this happen on Apple and Cherry as well, both later identified as ring shake - Ring shake is not always visible and sometimes it doesn't manifest until you get close to finish, Other times it manifests while the wood is drying - It is still ring shake any way you slice it, and I doubt it happens just to any one species.. Your wood being roadside, makes me wonder if that ring shake might not have happened while the tree was still young (since it is closer to pith) and could be caused by blast of wind as a tractor trailer goes speeding by, as easily as not, especially if it is while the young tree is more "bendable" (Just my thought on it, knowing how ring shake happens in the first place, but not knowing if it could be caused by wind blast from big trucks passing or what..) - Edit to add - And by the way much timber in our area was suddenly worthless after a tornado came through the region - even if tornado (or really high winds) doesn't take the tree down, Ring shake can still manifest, and as I understand it, timber buyers are gun-shy about buying standing timber that had been through an event such as that.. So, lot of trees in the area ended up being cut down for firewood.. even if they otherwise looked perfectly fine.Now I'm curious if there was an issue with just those trees? Anyone else turned sycamore with wood close to the pithe turning loose? These trees were freshly cut, only on the ground a day or two when I got them.
If they pushed these trees down with a bulldozer that can also cause the ring shake much like a storm.They cleared the side of the road to double the highway years ago and I got several 24 to 30" logs actually still have about 4 pieces I have kept out of the weather. Some turned loose first turning them and some came loose on the return...now I cut at least 4" out with the pith. Several trees there and they all acted the same. The problem that I had, there was no visible sign they were coming out but when hollowing out the inside of the bowl if I was too close to the pith the whole ring would release...I turned several beautiful bowls out of that wood, one of my daughters has one of the biggest bowls I've made, back when I thought everyone would want a huge bowl. I have not harvested any more sycamore, mainly for that reason. Now I'm curious if there was an issue with just those trees? Anyone else turned sycamore with wood close to the pithe turning loose? These trees were freshly cut, only on the ground a day or two when I got them.
Oh yeah that seems classic ring shake, in my experience, ring shake has mostly all been in the heartwood (I have had, oh, a good dozen or so bowls I had to cut down or throw away when the heartwood rings surrounding the pith, up to 4 inches away, came loose, sometimes while wet turning, sometimes while second turning, and sometimes just from drying) Apple, and Cherry for the most part, and I had a couple air dried maple (and cherry) flat boards come apart while cutting them down - the end checking was invisible until I was done with the milling (jointing and planeing to thickness and width) and started cutting them to final lengths, which is when the boards "fell apart" (resulting in a lot of unprintable words!) and I had to go and mill another new board down to get the boards needed for the project. I've since learned (the hard way, obviously) to inspect my lumber much more closely and how to spot ring shake defects in those boards. It can be difficult to spot in green logs though, it isn't always readily obvious, but again in my experience, it seems most common in heartwood rings (closer to the center of the tree) probably because that part of the tree is not carrying any sap or nutrients, it doesn't grow any longer, its denser and less giving, can't heal itself as readily as sapwood would.Gerald, I don't know or don't remember how those were dropped, I think I borrowed a triple axle trailer from work and they loaded the logs for me. They were cut and I don't remember seeing any damage to the trunks that a bulldozer would have made, I would have thought that kind of damage would be all through the trunk like the walnut I had did. I have looked at a bunch of threads in the forum some dating back to 2005 and no one talks about heartwood rings coming out. Probably the first three rings around the pith would peel out like potato chips one ring at a time, they were just cut down, slinging water everywhere so it was not a drying shrinking thing, just strange to me that only the very center rings would come out, kind of hard to envision damage that would cause that in a 30" trunk. Something caused it though...no one else has experienced it so it must have been unique to those trees.
