    You'd be better off putting the DC in an enclosure and venting the enclosure through that hole in the wall - that DC should pull 1200 CFM through an unrestricted 6" duct so would be be a lot better at venting fine dust from teh workspace.
    I would still build the enclosure for the DC, but I thought a powered exhaust fan in that hole where the vent is would vent the enclosure better than just the hole. I have a lot to learn about dust and air movement.

    Scott, if we can help you in any way or you need onsite advice please contact us via our website or PM me with your phone number and we can have a chat. If you want to see a system in place and get some idea of what is involved with installation I can do that for you as well. That is an open invitation to anyone who first needs to see a system and needs advice on dust extraction in general.

    Thanks Chris. I'm determined to find a time to get down and see you.

    Unfortunately that won’t work because the bathroom fan will act like a bottle neck. If it only moves 300 cfm and even if the DC is capable of moving 1200 cfm then the DC will still only move 300.

    Pity. I thought I was onto something there. I'll see how it goes with just that vent removed.

    Scott,

    I think if you end up having to locate your dusty inside, you're going to have to provide sufficient room for the exhaust by enlarging the vent, then so be it, I'm afraid. Down the track, what has been done can easily be undone, especially blocking up a 200 square hole in the wall. I'll leave BobL to present the strong technical case against restrictions in the system.

    Even with my gorilla of a ClearVue operating on all the major machines, jobs like sanding, even with a Festool Shop Vac connected, still produce an amount of dust which settles on shiny surfaces. I bought an air purifier from Hafco as a belt to match the braces.

    I would be keen for Bob's opinion on the belt to your braces i.e. the air purifier. I was going to get one of them anyway, but didn't know if they were all that useful.

    Air purifiers are useful for
    A) cleaning up a space in which dust is not being continually made, for say the purposes of applying a dust free finish.
    OR
    B) You already have a serious DC that is capturing most of the fine dust at source and you just want to remove the remaining fine dust that escapes the DC. If this is your only reason for having one the a couple of hundred $$ worth of exhaust fans will do the same thing , and they will never need cleaning or need filters replaced.
    Air purifiers are useful in heated sheds in cold climes when you don't want to vent your DC outside and lose all your warm air,

    Unless multiples of these are used they will not usually keep up with capturing the fine dust escaping any sort of half serious machine connected to a lower end DC.

    I have a serious "hospital operating theatre grade HEPA", air purifier but only use it for A) a couple of times a year -
    for B) I have up to 2600 CFM of forced air ventilation that work MUCH faster at removing fine dust than any conventional air purifier.

    I knew you would have a detailed opinion backed by real world experience. Thanks Bob.

    Okay, so the current residents in that building leave this weekend. And then the transformation starts. I have to 'unfurnish' that space and then start building benches and storage, so it will take a while given this is the busy season in my job in the real world. I have been collecting useful stuff and am running our of room to store it, so I'm pleased to be able to start.

    I'll be taking photos and posting them and no doubt seeking advice.

    Glider will be coming over sometime soon for a chat and a coffee or beer depending upon the time day, the Covid related movement restrictions and his beverage preference.

    I'm currently in deep cover at the farm, Scott. With the mouse plague to the West and Covid in Sydney, Oberon is a pretty good hideout.

    Except for that cold weather in Oberon, Mick.

    I'll see you when you venture back to the city.

    It's started.
    The shed has become a lockdown project.
    First step was to redistribute all the furniture. My teenage children ended up with a few surprises in their rooms and our Airbnb is a bit more congested - there are way too many chairs up there now.
    I built a cupboard last week for materials mostly. I made it out of formply for the strength and cost.
    1000mm wide by 600mm deep. The 'fat' doors are 140mm deep and the leading edge has a roller under it to manage the weight.
    Next project is the 6m bench beside it. This won't be for doing timber work on, but it will have a small drill press, sharpening area, charger etc.

    That is an extremely cool looking cupboard, Scott. Well done!
