Here's an alternative material for the mainline ductwork on your dust collection sytem.Use empty carpet roll tubes.Your 4" couplings and elbow fittings will fit nicely inside the tube.They come in about 10 ' lengths.If you have an "obstacle " in the way of duct routing ,the flex tube will fit over the outside diameter of the tube. Just cut the tube, and junction with a piece of flex tube routed around the obstacle. Visit your local carpet /flooring dealer, you can likely get all you need at no charge.Since they'te made of cardboard, there's hardly any static buildup, which improves the performance of your grounding wire.
