Seeking information about dust extraction

[Paul H (admin)]

My new Record 6x4 disc and belt sander works extremely well. Well enough to fill the workshop with a dust cloud....then I exit through the door leaving the dust to settle while I have a coffee.

Not the most stringent H&S process, even by EU standards ha ha.

I'd like to know what everybody uses for dust extraction and you might recommend.

I also have a table saw and various hand power tools that need dust extraction.

Any advice is welcome.

Thanks

Hi,
I work outside whenever possible, and wear a mask.
If stuck indoors how about one of these?

Hi, I used to use an old vacuum cleaner, which is fine for sanding but not much use for heavier chips from thicknessers, saws etc. You are forever emptying bags.
I now have the Axminster version of the one Steve found (since discontinued). It works really well, and has a huge capacity. The big hose supplied fits straight onto my bandsaw and thicknesser, you need an adapter and narrower tube to fit power tools like sanders, planers etc.
If you don't want to spend so much cash you can make your own from an old Hoover and a rubbish bin.
Always wear a mask. 😷

Cheers Grum.

I made up a home-made cyclone dust separator that runs from any reasonable powerful vacuum cleaner.  Lots of plans on the web, and you can by the cyclone unit relatively cheaply: https://www.ebay.co.uk/itm/Cyclone-Powder-Dust-Separation-Collector-Filter-For-Vacuums-Cleaners-Plastic-ABS/382153341597?epid=20010827688&hash=item58fa1d3a9d:g:gMQAAOSwOMdZXf7T ( this is the same as the one I have).  Bolt this to a bit of ply, glue a bit of sheet neoprene on the bottom of the ply as a seal and fix it to a stout drum to collect the dust (I found a strong plastic bin works OK).  Add a length of 50mm diameter suction hose to wherever you want to suck from, and connect a vacuum cleaner to the top port of the cyclone unit with a hose.

It works exceptionally well, and practically nothing reaches the vacuum cleaner at all, around 99% of everything just falls into the bin.

It is important to keep the dust out of the vacuum filter or you will
spend more time cleaning the filter than making dust.

The Paradox required quite a lot of whittling after assembly and I
found a sanding disc on an angle grinder was just the job. I started
with a vacuum cleaner to collect the dust but after a few cloggages I
left off the bag, put the vacuum outside and entertained the
neighbours with a dust fountain.

All,

Thanks for the feedback. I've had my eye on the Record Power version of the common drum extractors - about £128 from Mr Amazon.

I have 3 machines needing extraction. In priority order:  disc/belt sander (63mm port), table saw (63mm port), chop saw (35mm adaptor)

I'll need 3 blast gates for a proper solution and lots of pipe. The large hoses seem very expensive though, like £10 a metre or more. Timmo has 110m waste pipe plumbed around his workshop to each machine, I wonder if 52mm drain pipe could be used? Standard Pipe and fittings are relatively cheap.

I have a old domestic vacuum with a broken case that could attach to the cyclone thing that Jeremy suggested. But no fittings for the short hose, except vacuum machine 35mm-ish that fits the chop saw.

Dilys thinks buying a woodworking extraction unit with 0.5um filter is the first priority - one can add cyclones per machine later. I will need 100mm to 63mm adaptors though. Surely there is one true EU standard that Theresa approves?

Plan B could be open the door and point the sander towards the garden!

Working outside is safer, but I try to keep the noise down for the neighbours. The table saw is a beast and must be caged.

I'm glad I don't live down wind of any of you guys.

Don't whatever you do use plastic pipe, ie drainage pipe. There is a reason that commercial units use metal pipe. The current of air that is generated through a plastic drainage pipe creates plenty of static, hence the dust sticks to the pipe. When I installed dust extraction at work I used metal. The dust when plastic pipe is used sticks like _ _ _ _ to the outside of the pipe. The faster the air flow the worse the problem.

Don't worry, the rain soon sorts it out.

Ahh, perhaps the solution is to run plastic pipe round the workshop
so it collects all the dust by static attraction.

There's a fix for the static problem that I used in my old workshop, where I used PVC drain pipe connected to an old Vax vacuum for dust extraction.  Run a bare wire down the inside of the pipe and connect it to earth.  Someone else gave me the tip many years ago, and it seemed to work,  I used a bit of bare solid copper stripped out from some old mains cable.

I HATE dust; it stems from having a builder mix cement in my garage. I had to vacuum cement dust from every single item in the garage; every shelf, tool and scrap of wood.
Belt sander/linisher: if you rig a fishtail inlet to your vac hose and position it at the end of the belt or bottom of the disc it will suck up 90% of the dust.
Table saw: always outside, never mind the neighbours; they are mowing all summer long and shining their bloody floodlights everywhere. I too made a cyclone collector using not much more than an industrial pipe elbow to direct the airflow tangentially into a big bucket thing, with outlet in the centre of the lid, and placed in line with a vac cleaner. As Jeremy says, it works perfectly - until the bucket collapsed due to low pressure after a few years and then I got a Triton dust collector bucket, which you can connect two extractor hoses to.
Automation: My Triton table saw has a no volt switch with a very short lead and single socket into which I plug the table saw motor. I swapped for a twin socket and plug the vac into the other socket so it goes on and off with the table saw.
If the domestic staff are complaining about dust trodden into the house imagine what happens when you start treading oily sharp bits of stainless into the carpet!
