You can also always throw different thickness boards down on the cut face of the log and mill over the top of these.I just had an idea that i'm going to put to the test. Why do I even have 2x4's there to set the depth of the cut? it takes a long time to adjust and it is just a waste. All I need is some more nuts and washers! then i can cut slices as thin as the nut and washer. I can adjust the depth without adding and removing tiny 2x4's...and i can be more precise with my cuts!
