Anybody have any experience milling pin oak? Customer wanted his tree milled. Tree was felled 8-1 0 weeks ago. We have an old Enterprise circle mill from th 1920's with a 1960's John Deere industrial 6cyl. Of about 100hp. The blade is 56 inches with 52 teeth with a 6-7 guage . RPM is 550. Log is about 20 inches we opened the log and about 6 feet into the log (12 feet long) the can't started twisting and binding th blade. We backed out and we cut on the same line and the kerf ran deeper into the log and bound up again. After trying all 4 sides (eventually easing through )We had a visually twisted can't. We have experienced this with larger white oak but this wood seems much denser and harder to cut .
If you cut w. oak it's not you. Sounds like that tree was in a wreck and healed and grew and you took it apart.
Good possibility on the white oak Was an old tree and we have a lot of severely stressed trees here The pin oak was planted 30 years ago by the customer and was not damaged according to him. The growth rings were wide and I read somewhere that adds density
