This post was prompted by a question in another forum about dust collection.
FIRST - Graphite dust in the air is a bad thing. A great solution to
keep the dust out of the air when cutting shafts is a wet tile saw.
This one has gotten good reviews:

SECOND - Planning a dust collection system is a serious business. This
site is an AMAZING resource (John are you listing?)

The site is geared toward woodworking, but contains more information
than you thought possible about dust collection. It covers everything
from health concerns and planning through built it yourself dust
collection projects. Do yourself a favor and spend some time looking
through it.
