(see figure 5).

This is best done on a lathe by
removing a bit of material from
the inside so that the nozzles
fit snugly. See images attached
to show what we did. I also
wired the machines so that the
vacuum starts whenever either
key machine is turned on and

valves to switch suction from
A couple of import key
machines are said to have a
vacuum port however most do
not. This system could easily be
adapted to many other styles of
machines. Just make sure the
vacuum nozzle is positioned
in such a way as to not block
