Sawing Big Log Butts
From contributor A:
Contributor J is correct. Slow the carriage down and make sure the blade is sharp. For large logs the set in the blade needs to be about 26 thousands each side. This will help minimize the wavy cut.
From contributor B:
It will also help if the log is loaded small end toward you... Sometimes cutting into the butt end, especially on large flair butted logs, the blade has a tendency to rise.
From contributor T:
You could have a couple of fixes. Saw your logs while green. If they are a couple of months old or more, depending on species, you could have, as you say, dry ends that make the mill work harder, making the blade deflect. If the butt end is much larger, the mill will have to work harder to cut this wider butt. Again, the blade will deflect, as something must give if the work is more for the mill. Sometimes I buck logs longer than I need, knowing that by the time I saw, the ends will be dryer, and will create a problem. I cut off the ends when I am ready to saw, using the ends for firewood. I know, it is a waste, but I burn wood and I mostly saw for myself. Be sure to use Anchorseal immediately after bucking the trees into logs. I mean within 1-2 hours. This will help with your problem, but will not solve it if the butt is much wider than the rest of the log. Just slow down when you get to the butt.
