Just got a Monster Mill MM3-1. When it came the one roller adjust knobs was loose so I had to remeasure the gap. I tried to get it to the factory default of 0.045 but it may be a bit less as it takes a bit of force to get the feeler gauges in and out. I may try remeasure, and not make it so tight on the feeler gauge unless it is supposed to be. Here are a couple of pictures of the crush. What do you think of this crush? If you have an MM3-1 what is your gap setting?
