Wheelie Bin Dust Separator
I had a spare wheelie bin and decided to try it as a dust separator. I cut two x 100 mm holes in the lid and fixed two pieces of plastic conduit as an inlet and outlet. the lid was sealed using a rubber door seal and I had intended to fix a latch to hold the lid down. However, the first test proved that the lid will seal itself under the suction.
The bin does not show any tendency to deform when in use and I reckon that it takes up less room and will be easier to empty than a 44 gal steel drum.Jim Grant

Great idea mate and as you can get spare lids , making a set of releasable pivot pins you could just wheel it out for the pick up once a month or so if you can't get rid of it any other way lik in the garded etc
Like the idea will use as I have an extra wheely as well Thanks

I considered that option when i bought my 80L bin at Bunnies (see Wongo's 2 stage dust collection thread). The only thing that stopped me was the price of the wheely bin (around $80 I think) and the fact that i thought it would be more difficult to emplty than a simple plastic bin.
Anyway, good move. I think a couple of Occy straps over the lid would help seal it better.If at first you don't succeed, give something else a go. Life is far too short to waste time trying.

I am just about to do the same thing, only I will be using 12mm ply for the top, held on by clips. If the top is removable it will be easier to empty in the garden
If it goes against the grain, it's being rubbed the wrong way!

funnily enough the wheelie bins around my area have been disappearing for years... so much so that the council arranged an amnesty where no questions would be asked if the bins were returned within a specified date.... Now I know whats been happening to them

Jim ,do you find that using a bin that is really deep like a wheely bin improves seperation ? and did you face the inlet pipe inwards to create a cyclone effect? and last but not least, how much large dust still ends up in the bag, is it a lot still or mainly just dirty air ?...

Dust Separator
The wheelie bin works fine for chips and heavier shavings off the jointer but the dust from the saw mostly lands up in the dust bag. I didn't try to create a cyclone effect as I only wished to separate the bits I didn't want going through the impellers. The difficult part was getting the conduit inserts to adhere to the plastic bin lid. I guess that the plastic is designed for things not to stick to it. In the end I used Araldite as the glue and a sealing adhesive to get rid of any air leaks.
It's not pretty but it seems to work OK.Jim Grant

Thanks Jim
Was working on installing the 44 gallon seperator this morning when the neighbour came in.
His place of work apparently used to make them and have a few left over. He is dropping me off a couple tomorrow. Just need to supply the axle s and wheels as they were not made at the factory.
By the look of your it is a much better idea.

150mm version
I did the same thing with a big wheelie bin primarily to stop damage to my 2hp DC. I have it plumbed with 150mm PVC and a thick piece of MDF as a top. I angled the inlet to encourage swirling but not expecting high separation as for a true cyclone. I find that until it reaches about half full virtually nothing gets into the DC bag. I am happy with this until I have the time to build a proper cylcone.
The MDF lid is located by a bolt at each corner but I have found I do not need to actually put a nut on as the suction holds it on and seals really well. It is impossible to move when the DC is on.
I organised it so the top can be lifted up enough to wheel the bin out for emptying. Not sophisticated but works well enough whilst I am still time challenged !!

Hi folks- Just got myself a carbatec thicknesser with a three hp single phase motor. I now want to make a dust extractor-I have the wheelie bin but that's all-any ideas of where to pick up a suitable motor and fan? What hp will be sufficient and will the electricity supply to my workshop be sufficient for two motors running at once?

Jim,
Is the extractor unit appears to have a cloth/felt bottom bag... yes / no? Is it a Carbatec? If so what model? Mine has a plastic bottom bag which is a bit of a hastle to refit.

In some councils (Casey), you can get a extra recycle bin (a large blue one) for no extra cost (you just have to phone up and ask).

So simple; so good.
A simple refinement that would not affect its efficiency but which would further reduce the risk of larger chips going through to the fan, especially as th bin fills up, would be to make the outlet pipe from the bin twice the diameter than the inlet pipe. This would slow the airspeed there lower than that needed to pick up larger chips. The design theory and practice including airflow volumes and speeds is well explained at:
