The mill blade taped holes were out. I had to increase the size of the holes to match the the taped holes and drill the counter sink deeper. The front hood had cast excess that had to be ground away. And one side had to be ground flat enough for the wing nut to catch and not slip off. After I finished the work that should have been done prior to leaving their plant, it does a pretty good job of milling. Mill a cup of corn to shed the loose metal coating before use.
