Alaskan problem

Could it be the angle of the outside of the log causing the mill to rise up? Its hard to explain but I've seen it happening when I've been chainsaw milling before. Where the side of the mill gets pulled into the log as you're cutting it can be forced upwards sometimes.

Yep heard of this one before. Had an Aussie lucas miller explain it to me a while back, basically chains and blades are designed to cut perpendicular to the timber. An angled wood edge means one side of cutting edge is doing more work than the other, putting a minute twist into the cutter whilst the other side is lazy on entry, and can if given too much force, start cutting off line.
Def another possibility.

are bars invertible?

 

if so flip the bar and you will find out if that is the cause won't you?

Hi guys I think it maybe what James pepper pop said as the butt is quite fluted and if the mill was running on an upward curve , but will obviously resharpen , dress the bar etc and let you all know how I get on
