    Default The scary result of ZERO dust extraction in a cabinet.

    "Red Shirts. The innovators in stupid ways to get killed and wreck stuff."

    First up...I know, I know ...so please withhold your chastising.


    This is what the motor from my TSC-10HB cabinet saw looked like when I opened it up today in an effort to troubleshoot why it suddenly stopped spinning up properly. It's probably only about 80% of what was in there while it was still sealed up.

    I'm doing the repair details in another thread over in the table saws section, but I wanted to show the dust aficionados what the potential effect on seemingly well sealed motors is by having no dust extraction whatsoever and sometimes letting the saw's cabinet get stupidly full before cleaning it out.

    Hopefully this truly shameful and grievous error of mine will inspire other messy slobs like me to get their act together and look after their health and workspace (which shouldn't have a permanent and increasingly heavy layer of dust over everything). And if not themselves, then at least the expensive machines, tools and combustible things they like to use, live and work in.

    HAH!!!
    After some multi-meter tests I was expecting to see about half of the stator covered with carbon and a whole bunch of ash.

    Added bonus: I learned a bunch of new words/things from a sparky mate

    It depends what you means by conductive.
    It's unlikely to become as conductive as say metal but
    It would need to get wet, or at least damp, and be well compacted together and the path length be short ~mm.
    Other contaminants in the sawdust (in my case ants and act poo) can also lower the resistance.

    Everything is 'conductive' just some things more so than others.

    My dust extractor motor had dust just like that compacted in there when I got it from my Dad. Only thing was it was buried in about 3 feet of saw dust since it hadn't been working (due to being full of dust) for about 10 years!

    Sorry my comment was made more tongue in cheek
