I just ordered a 100 mm flat rolling mill (Grobert). I bought it
without the 4:1 gear reducer. The reducer is an add on, so I can
buy it and bolt it on at any time. The dealer I bought the mill
from told me that he almost never sells a gear reducer with a mill.
The purpose of the gear reducer is to make it easier (takes less
energy) to use the mill.
So my question is, can anyone comment on the pros and cons of a
4:1 gear reducer.
