Have you looked at Bill Pentz's cyclone webpage? He has a ton of info
on cyclones, and basically says that almost all consumer-grade dust
collector/cyclone stuff available now is OK for collecting chips, but
does nothing to help with fine dust, which is the dangerous part. If
you keep working outside, you're probably fine, but it's something to
consider.

What is dangerous about the fine dust?
