Yeah, I probably should have checked this a few days ago when suction felt weak but, then I wouldn’t see this mountain of plastic chips.
You can build one of these yourself for the cost of 4 buckets, some rocks and pvc fittings from your local hardware. Checkout Chris Notap’s build here:
Or, if you want a bigger collection can, you can make your own Thien filter by cutting out the parts from whatever sheet material you have on hand on your CNC to fit a steel garbage bin!
I added weather stripping around my can for an air seal… My Shopvac can cause the garbage can sides to pop inwards if the hose flow gets blocked.
I use a similar can to hold the waste from my clear vue cyclone. All the complicated parts are in the cyclone and not the can so it fills all the way up. The problem is dumping it. I can’t put a bag in it as it would get sucked up. So when full I have to transfer into a bag. That in and of itself is a mess and a pain.
I have considered making some sort of rig with hardware cloth or something to hold the bag open in the can and then pull that out before pulling the bag full of dust/chips out.
The steel trash can doesn’t collapse… Not like a Rubbermaid plastic one which will practically fold-in on itself. But the sides will pop-in a bit from the pressure differential.
No you can’t put a bag in it(though maybe you could… I haven’t tried to see what would happen… Would the bag get caught up in the airstream before enough dust settles in it? There should basically be zero airflow thru the can sides/bottom… I may just have to try this) , but I find it pretty easy to empty out into a bag with very little dust escaping.
I wouldn’t want to use a bigger trash can as that would end up being overly cumbersome.
The wall-hanging dust deputy has a grate that goes over the bottom of the bucket, to keep the bag from getting sucked in. You could rig something similar pretty easily.
