They call that tension wood, if you moved the logs farther forward would you be able to cut through without using the winch but i guess it would be more walking to get to thickness control.
Wow that was an interesting log. Even at the beginning the log seemed to be moving because you needed to take extra very thin cuts to make the face flat. Thank you for sharing this video.
Thank you for your comment. Good question. Thank you for watching.(*^_^*) If the fixing is insufficient, the log may move a little. It must have moved while I was backing up and disconnecting. The log this time was bowed, so it was uncomfortable to sit.
