Yea, I learned about leverage. I had a 2&1/2" square stock held in the smaller vice to the left in the second pic. The cut got too big, as the tool dug in the stock, the movable jaw of the vice broke. Its now held back together with 4 screws, and 3&1/2" over size screws for the jaw. I'm still new to having power feeds for the knee, and had the table X axis, and the Z axis moving at the same time. I needed a bigger vice anyway.
