Mega mega growth rings for a Willow Oak. It was near a soccer field, so it got plenty of irrigation runoff.
It's a holdover from when I tried to run 3/8 20 on my 550. I got some with the right name on them but trying to wear out that Husky bar since I don't have any other K095 saws that will run it to my liking. A Husqvarna branded Oregon bar on a Makita branded Dolmar saw. lol
