I've been pretty frustrated with matching price, availability and fit for
putting together a dust collection network for my shop. This seems to be a
common quandry, as described on one of the dust collection websites. I've
discovered the ductwork sold at Lowe's made by Gray Metal South. In addition
to the flimsy 30 gauge stovepipe style, they also have 26 gauge fittings and
pipe. It looks like it will do most of what I want to do, especially in the
6" part of the network. Forget buying anything larger than 4" at the local
woodworking shops. They simply don't believe in it.
Has anyone used the Gray Metal South ducting? It looks like I can expect to
do some careful sealing, but I see no other disadvantages.
By the way I'd gladly use S&D PVC pipe, but fittings for it cost a fortune.
