That is the softest wood I have ever milled, I milled the first log, 6 slabs @ 8 feet, with "NO" sharpenings. I didn't touch the chain when I started the second log. When I screwed my guide board to the second log, I put one of the screws at a slight angle, figured I had plenty of room. I was wrong, nicked the screw. Bought a new chain, too hot and tired to sharpen, and it milled 14 more slabs @ 7 feet, out of the last two logs. This morning I went out and milled 6 more Blue Spruce slabs, and it's still pulling hard. I've got one more small Blue Spruce log and I'm going to keep going till it starts to slow down. I have a dead Red Oak to mill for a friend, I know that will knock the edge off quick. You can see the two Blue Spruce logs in the background, Joe.
