    20190921_122301.jpg Rather than use the time-honoured but laborious process of chasing out for new boxes and conduit, I thought I'd use my angle grinder and diamond disc. The trouble is it makes a hell of a lot of dust.

    Thinks: "What can I do to keep the dust down?"

    Hmm soil pipe bracket looks like a good starting point

    Source a piece of PVC left over from a bathroom project

    Mark it up and trim to shape

    Stick it to the bracket

    A piece of 1 1/2" waste pipe is about right for the Henry nozzle

    Attach it and open a port

    It woks after a fashion, but still a lot of dust. Modification called for.

    An old shelf divider came in useful

    A little bit more tweaking and it fits

    It's not perfect, but it has kept the dust to an acceptable level. Total cost - £0 (apart from the bottle of solvent adhesive I had to buy when mine ran out :rolleyes:

    Brilliant bit of engineering and incredibly simple.

    If I can make a suggestion you will have been better off fixing the extraction port to the other side. That way you are using the ejection velocity from the rotation of the grinder to entrain the dust into cowl thus making the contraption more efficient

    I wanted to make something that didn't affect the guard. The extractin port is aimed at the periphery and the disc rotation throws the dust towards it. I think I really need a centrifugal dust collector now since the bags do clog quite quickly.

    Still, I've saved myself £57 by making one :sheep:

    That's my intention. At those prices it's really not worth going to the effort of making one, is it?

    Seem to remember a car mag years ago with this sort of stuff suggested . . . then the next month printing a "don't do it ever" article due to the duct potentially being explosive (simply because it's dust, not because the stuff is flammable) and going bang as it went through the vacuum cleaner . .. so be careful of your vacuum cleaner

    Been meaning to make one for a while.
    Bits arrive next week.

    Usually work outside when possible but over the last 4 months inside bedrooms the extractor has been a blessing.

    Got so used to it I'm running it outside to reduce cleanup too.

    The cyclone should make emptying quicker and cleaner

    I got one of those & attached it to one of those 25l blue plastic mini barrels. Used it with my festool extractor & it was working well until it sucked the barrel flat! I'm now in the process of attaching it to a 20l heavy gauge steel oil drum.

    I was planning on popping a couple of dowels in a cross across the diameter.
    Won't restrict emptying but should stop the vacuum crushing it.

    Il be using a steel drum with a Henry attached to the top in my shed. Will also put casters on it.
    Il post the video in a sec.

    Not having much luck
    Bucket turned up today. Some muppet poked a hole through it installing the handle.
    Gave up got a refund and ordered one of these. Much more suited to being thrown around the van
