Any chance it was just the sawdust plugging up the chain and binding the bar in the cut?

Red Oak is bad for that.

 

Straight wood can contain stress, I see it when milling lumber on occasion..

When the band blade leaves the log the board will lift up off the cant.

Without the stress the board just lays flat.

i dont think so kevin, it would have kept doing it if that were the case...it happened on each cut at about the same percentage of the way through the cut.

In the spring and early summer months the redwood bark 'cambium cork fibers' can bind a cut. Major sometimes. Also happens in the black willow and Eucalyptus. But in either case it's the bark binding the bar, very distinctly, and not the wood.

 

I've had pine and fir bind on occasion just like you had Steve, and I could only attribute it to some kind of tension in the stem. Not by gravity, but in the log itself.

thanks gerry, very odd how it was at the same point in each cut...that wasnt coincidence, so there must be a specific reason for it.
