I love my lab's shopbot desktop, but the stock dust collector was broken when it arrived (see 5th image in gallery). The rest of the machine is very solid and performs beautifully, so I wanted to give this machine the dust collector that it deserves!The new design features a magnetic attachment (similar to the OEM design) and an o-ring sealed telescoping vacuum attachment. Magnets used were K&J's countersunk R622CS-N. O-ring is Buna-N Dash 325.
