I needed a good way to install the main duct runs of my dust-collection system, and I wasn't looking forward to the prospect of trying to raise a network of pipes to the ceiling by myself. The system shown, using 48" cable "zip" ties and furring strips, provided the solution.I started by screwing furring strips to the joists along the path I wanted the ducts to take. I then laid the zip ties across the notches in the furring strips and zipped the ties into large loops. Next, I fed the duct parts through the loops and joined them. With the ductwork still hanging low, I had no problem sealing all the way around the joints. Once the duct was joined and sealed, I raised the entire labyrinth up to the ceiling by slowly ratcheting up the zip ties.—Bill Goggin, Alma, Mich.
