At one time I was looking a making my own rolling mill, but I ran
across a less expensive version and bought one instead. Now I just
make my own rollers, actually, I have made 2, but I figure if 2 came
out ok I should be good on any others I choose to make.
Rolling mills have two gears which engage, one on the lower and one
on the upper roller that is what makes both rollers roll at the same
rate. When separated farther than the gear teeth can touch they stop
rolling together. The Durston has a cover over these gears, I have
one of the cheaper varieties and there is no cover on mine so I get
to see the gears work. There is nothing wrong with your mill, you
have just separated the rollers to far apart for the teeth to engage.
If it has not happened to you yet, sometimes the teeth on these gears
hit dead on and you can’t get the rollers to go back together, simply
turn the handle while you bring the rollers back together and you
won’t have that problem.

The gears on the left side of the picture are for increasing the
torque of the crank handle and the small ones you see on the right
are the gears that make the rollers work together. When you opened
yours up, the 2 gears on the right separated, and the top roller
stopped rolling. The bottom roller is the one, gearing wise, that is
directly connected to the handle on yours and mine.
Hate to say it, but for my two cents, re-pour your ingot or hammer
it down on an anvil.
