When I first setup my MM-3, I used different settings and marked the end plate with a Sharpe so I wouldn't have to use the gauges again. I started at .030 and went up to .045. Fred was easy to deal with and responsive, but I bought mine when the company was first formed. I found that mounting square to the base was imperative. They didn't have a hopper for sale when I bought mine and I quickly found my feed hole was too wide. It seams like anytime you purchase a product these days the instructions are lame. I do think it's the best mill out there. I bought a mega old skill 1/2" hole shooter for mine. Works great now! It did take some tinkering to get it right though. I just took mine apart and disassembled it. I was shocked to see how much grain dust had made its way into the bushings.
