Lots of people recently have asked to see an overview of the extraction system in my workshop, so whilst waiting for some stuff to arrive for a project video, I took the opportunity to satiate their desire.
The system I use is pretty much an inline run of workstations, each connected to the 4″/100mm extractor hose (see the video and below for links) which sucks all the dust and stuff outside to the extractor unit which sits in a shed I built next to the workshop (left).
On top of the two lathe stations is a single Blast Gate which simply allows air to flow into the system when it is open. When closed, it cuts off the airflow into the hose. In order to have maximum suction at the machine I am using, it is important to have all the other gates closed as tightly as possible. Pretty simple really, but the purchased gates I’ve got are not great, so I made my own. Here’s a couple of pictures, one with the measurements. You should be able to figure out the sizes if I missed anything off.
After making my own blast gates from 6mm plywood and making sure they had a really tight, snug fit, I found that they are actually better than the shop-bought ones, which was rather pleasing!
Each of the lathes also has it’s own ‘dust hood’ which focuses the suction towards the lathe to collect the dust when an item is being sanded.
In the video below, I mention Paul Jones prompting Bill Pentz and his reasearch into health issues of woodworkers together with his own diagrams of cyclone extraction. Please click HERE to visit Bill’s his website and have a good browse round – it is full of brilliant information..
Shopping for Extraction Units
If you are looking for any of the bits of kit I mention in the video, here are some useful links for you. They will take you to your local Amazon or eBay store and search for the items required for your own extraction set-up. Before purchasing, please do some research on what size unit would be most suitable for your workshop. Thanks.
Mine is an Electra Beckum SPA1000 which is now discontinued.
The SPA1000 ‘sucks’ 1000m3 per hour and is more than enough for my size of workshop. Please check that the units linked to are suitable to your working environment.
Here are a couple of links to units available on both Amazon and
4″/100mm Tumble Dryer Hose
This is my thrifty alternative to the expensive black piping that are sold with and for extractor units. It is pretty tough for the job it needs to do and for the price of it, makes for more than a suitable alternative (and more flexible) extractor hose – especially considering it will mainly be carrying dust and small chippings/shavings. Find it on Amazon and
Various Extractor Joints
You need to get your hose round corners, and whilst the hose is good enough, it is better to have tough elbow and T-joins to assist. In my system, I have three ‘T’ joints, two 90 degree joints with a reduce on one of the ‘T’s.
Here’s some on Amazon and
With all the hosing winding it’s way round your workshop, you’re going to need some brackets to tame the snake-like tail from flopping around.
There are loads of different types on the market, but these links to brackets will be helpful on Amazon and .
When all your work stations are in the right place with hose running to them, you will need the ability to shut the ends of the hose off, leaving just the station you are working at open. For that you need blast gates. Again, there are lots on the market. Some are good, some ‘will do’. Or you could make some like I did!
Here are some I found on Amazon and
