It's worse than that... Do those long green shoots look familiar to you? They hang down on a living tree that is still upright. As spring progresses they turn an almost neon green color. It's a tree that loves water and grows fast as evidenced by the large growth rings. Stick one of those logs in the muck and it just might grow a brand new tree
The OP called it right, I just did my best to help him figure it out for himself. I had faith that he'd get it eventually I'm a huge believer in the "teach a man to fish" approach.
Learned some valuable lessons on raker height and dirty bark yesterday. Turns out you actually have to gauge each raker individually and you can’t just take the same amount of swipes from each one. You don’t want all your rakers to be the same absolute height (counting swipes), but rather the same height in relation to its tooth (using the gauge for each). As you sharpen your chain inevitably some teeth will be taller than others so it follows that rakers will rarely all be the same absolute height as the chain is worn. Doing that helped quite a bit but then it just totally quit cutting after the first slab. I thought it felt like a dull chain but that can’t be the case because I just sharpened it, haven’t hit anything and I usually get 8+ slabs between sharpening so I shimmied and pushed my way through. As soon as I started the next cut I knew it was somehow dull and stopped to sharpen. Turns out the bark can dull a chain real quick depending on what’s in there! After the raker tuneup and an additional sharpening, the black walnut production hit full swing. I even debarked one of the logs and it cut amazing!
I found the progressive raker filing guides after hitting metal multiple times while milling. Each time it damaged one side of the chain only and as I filed damage away the chain began to cut very crooked (using those sit on top of the chain raker guides). So much so that it bound up the mill and I couldn't push anymore. A little research led me to the Husky branded ones. One tune up with those and it was back to cutting perfectly straight. I not so long ago bought the WCS plate and it works great. The options of aggressiveness allows me to fine tune the bite to my ported saws. Check it out if you haven't.
Look like elusive shagbark to me, but there are a couple other varieties that look similar that aren't common around here.
Found some storm damage black locust to remind me what it looked like. Should be able to get some 8ft 4x4s out of these for raised beds
