Articulating Dust Collector Arm
These linkages are designed to connect 2 1/2" Schedule 40 PVC piping to allow for an articulating dust collection solution. The base requires a 19mm steel bar for support (if you want it to rotate). I also used a thrust bearing and some washers, but I'm not sure they're required. For each of the linkages, you'll need a 100mm o-ring for friction and a 6" 1/4"-20 carriage bolt and knob to tighten the two halves.
