blade rises while cutting and jams in kerf

[fruitcakesa]

Like the title says, I start milling and immediately the blade begins to rise and flex and jams. I have been milling these hemlock logs for past few days with no issues, in fact, the log I sawed today prior to this one cut fine.
I considered wonky grain in the log so tried cutting a different face , no help, and then flipping it end for end, still no joy.
I then put a different log on the mill and got the same result. It was from a different tree BTW.
Blade tension is good, the guides are properly placed and the blade had only cut the one log prior.
I am going to try another blade just to rule that out.
Any ideas or advice? Thanks

A new blade solved it.
The "bad" blade, which cut the first log fine, must have somehow gotten dulled during the cut. Maybe an embedded stone or sand in the bark from when it was skidded out of the woods.

Either the teeth were dulled, or the set pushed out.

They call them bars, not blades. Think about it a blade is sharp on at least one edge.

I'm pretty sure he's got a bandmill, where blade is what its called.

You do not mention mill or blade type, but common problem with chainsaws when hand filing; many seem to press harder or take more file strokes on the 2nd side when they flip to alternate cutters... thus the saw moves to the side with Longer cutters. If cross cutting, suddenly cutting curves, milling it always binds. Once bought a cheap 7" circ saw with cheap steel "free" blade, first attempt it wanted to cut circles vs straight line... took a few minutes of inspection to realize the blade had all cutters bent to same side vs alternating.
