No Charge for Dust Collection

Want to save money on your dust collection system? Try using discarded cardboard tubes from rolls of carpet or linoleum. They come in 12” lengths and usually have a 4 1/2” outside diameter and 1/4”-thick walls. Cut the tubes to length and join them together (and to your machines) using plastic T and elbow connectors.

To reduce the o.d. of the cardboard tube ends to fit inside the plastic parts, install a dado blade and set up a stopblock on the radial-arm saw as shown. Lower the blade until it barely touches the tube. Next, start the saw and rotate the tube by hand. Repeat, lowering the blade gradually and test-fitting until you achieve a snug fit in the plastic connectors.
