Is there something about coffee from a country that uses the
metric system, that has the opposite effect of coffee sold
in countries that use the English system?

Kidding aside, the videos I see of simple vibrating feeders
seem to indicate that it should be viable to just add a bin
with a flat bottom to hold the screws near the beginning of
the feed.  

The version at  https://www.youtube.com/watch?v=mnoKHHNhiiQ
has a great illustration showing how the sorting works
at the 14 second mark. In the comments they say that it is
about 90% effective.

P.s. there was actually an earlier message I sent, that has
yet to show up on the list.  Apparently the lag I often
experience is not the same from minute-to-minute.
