Glad you brought that up.
I'm wondering if I really need 26 gauge ducts. Home Depot has all the
fittings I need but they are 30 gauge.
I bought a 2Hp cyclone collector but haven't bought any duct work yet.
If you buy 30 gauge ducts you will ruin them the first time that all of the
gates get closed while the dust collector is running. The vacuum created by
the 2 hp cyclone dust collector will be enough for atmospheric pressure to
squash them. Smoke pipe for stoves is 26 gauge and is readily available in
black or galvanized at every heating equipment wholesaler. The seams on it
will leak if they aren't sealed, but it won't collapse from high vacuum.

1.) Are you related to Rube Goldberg? <G>
2.) Is there any possibility of sucking sparks from your grinders into
the same tubes that carry wood dust? If so, that would worry me. A
spark could possibly start something smoldering that won't get bad for
hours, long after you've left.
--Yet another reason why I keep the vacuum somewhere other than in
the shop, but yeah there's a risk. Fortunately most of the metals I work
with are non-sparking; i.e. brass and aluminum. When I grind steel I wear a
dust mask and make a mess.
