I added a seperator to my puny 1 HP unit along with a larger top bag.
While the larger top bag didn't make much difference, I noticed an increase
in performance with the addition of the seperator. I assume this is from
two things. First, the bottom bag doesn't fill up nearly as fast. Second,
I think the 45 gallon trash can is acting like a vacuum tank to a degree.
Of course, the seperator is much easier to deal with when it comes time to
empty. With a good stack of boards, I've produced three trashcans full of
fluffy shavings in an afternoon.

As I am waiting for the delivery of my dust collector, I have been
planning
out the piping runs and the upgrades that I will be making. I already
have
a Wynn filter here waiting for it. I have been thinking about the need
for
a separator this whole time. My understanding is that there are two
primary
reasons for a separator. One is to reduce the frequency of bag changes,
the
second is to protect the impeller and the filter from sizeable chips
coming
through and damaging one or both. In the couple of weeks since I got my
new machines (TS, jointer and planer) I have noticed that none of them
produce chips that seem to be potential sources of damage to my DC. The
TS
produces mostly dust, as expected, and the jointer and planer produce
mostly
fluffy shavings.

My question is what kind of machines or what kind of operations produce
the
kind of chips that will damage a DC?
