Duct and Fittings-- Where to buy

[Vince Heuring]

Is there any place to buy dust collector duct and fittings in the Denver/Boulder area, and if so, where? I'm trying to find 4" and 5" 26 ga. duct fittings without buying them from Penn State.

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.

Thanks, but Woodcraft lists only plastic fittings, and Rocker, OTOH, lists only spiral duct.

In Albuquerque there is:

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.

I was afraid of that. It would have been just too easy to get the stuff at HD. I guess I'll try the heating/cooling outfits. Thanks,

Two questions:

1.) Are you related to Rube Goldberg?

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.

--Nope, I'm 'home grown', heh.

--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.
