I need to build a workbench and I don't have a miter saw. I've been able to cut a 2" x 4" square in the past, but it was after a lot of practice. With the price of lumber these days, I don't want to be wasting the stuff for no good reason. Do you guys have any tips? I've seen the pros cut a 2" x 4" perfectly square without even trying. They don't mark a line either. Amazing.
