Thread: DIY Over Arm Dust collector

    DIY Over Arm Dust collector

    Just completed my version of the overarm dust collector. The commercial versions go for $300-500 depending on the manufacturer.

    A few improvements over the typical commercial versions:
    1) Gate built into the collector for easy adjustments. I happened to have an extra 4" gate.
    2) Ported for 4" instead of the typical 3"
    3) Counter weighted to be perfectly balanced. I think the SawStop version uses a spring, so this might be a wash.

    When not in use, swings out of the way.

    Comparison for 5 cuts of a pine board, with an open ended cut, since open ended is virtually guaranteed to throw out dust.

    Without the dust collector, just in cabinet collection.

    Your pics arenít showing up. Please upload them to the site so the kinks donít get broken in the future and we donít see small white boxes like we see now. Looking forward to seeing what you did!

    Thanks, first time trying to post project pics. Hopefully they're showing up now.

    Just wondering why you put the vertical pipe to the left of the blade? I assume you don't work with sheet goods?

    Depends on what I'm doing, if they're large I usually use the circular saw. Really though, it's easier to pull the fence over to the other side of the blade, and cut that way, since there's more support that direction. Finally, worse comes to worse, I can just remove the pipe, since it's deliberately not screw in, though with my current garage setup that wouldn't really get me much more room, say another 6"-12".

    Looks good Andrew. The amount of change with the overhead collection looks similar to mine. I was hoping it would get more but it gets most of it, definitely not all.

    Thanks! I think to get more you'd need to physically block the stuff that shoots out the side on an open cut. For a closed cut I get virtually no dust on the table top.

    I've seen swing down side pieces that seem like they would address the issue, but I'm happy for now with the results I've gotten.

    This is an excellent example of side blocking for open ended cuts.
