"But I found that when I was getting to the right side after cutting the left side, that the right side started to move. I had to go back and tape it in place.. Any suggestions? Anyone
( I wrapped clear tape around the boards before cutting )"
Rather than cutting one side completely off, then the other side, I drill a starter hole at one end and complete the cut as an inside cut. this keeps the stack from traveling as it is attached right to the end. I hope you get what I mean as the explanations doesn't look that great.
