The old sloping back cut makes me want to discuss and learn the finer points of sending the butt off the back of the stump. Is it acceptable to put the back at a slight upward angle towards the face? I have accomplished the task with face angles and a level back cut about kirf lower than the face cut. The results are not always favorable however, and I believe it is due to not getting the angles right in accordance with the way the trees is growing. . If I had to send them off the back like that all day I think I would just have a piece of aluminum stock to lay in the face until I had the methods down.
So maybe this sloping back cut reference will scare up some interesting conversation anyway.
