After sawing the bulk waste parallel to the knife line, I have been using the bevel away from the knife line on side A of the board, essentially paring the waste to the knife wall about half way down the wall. This works normally, as if I had chopped out the waste.
When I flip over to side B of the board, the left over waste (now unsupported) is where the difficulty arises.
I start paring/shooting small increments of waste (bevel away), and by the time I get to the knife line the torque has already started the breakage below. The resulting shoulder is still clean, crisp, and undamaged. It is about 1/16″-3/32″ below the shoulder where the breakage occurs the remaining way to the half way point where I would meet the side A stopping point.
Smoky Rick, I may try to do what you describe with a narrower chisel. Shoot to the sky, but at an angle from the edge of the waste.
I am located in Belvidere, also in the tundra we call the middle of Northern Illinois. Quite enjoyable weather lately, Brrrrrrrrrrrrr.
It just came to me that I could probably shoot the to the sky with the saw on both sides and get closer to the shoulder, leaving a more controllable hump in the middle. Maybe I need to work on my fret sawing instead.
