Semi-chisel square next time lol.
What was it about that wood that killed your chains?
Look forward to the pictures.
You can not square file semi chisel, and square mills so much faster than round.
The dead/dry/hard wood was killing my chains. I normally get 4 cuts / chain with Oak, only got 2 passes with each 36" chain with this one, and I had to really push the saws to get them to cut. Toughest wood I've ever milled. Also, FYI, you could see the grain was twisted.
