Dust Extractors/Cyclone
Been trying to rig up a mini cyclone. Seen a few sites on them but how far down the cone does the vacuum tube have to be? If its in the cone wouldn't it suck up all that stuff that's going into the botom bin? All the pics I've seen have that part covered. At the moment my dust extractor is just the atmosphere at the backyard-the stronger the breeze the better the extraction. Nuisance having to lug the workcentre/ext table outside-Just got it covered with some plastic sheeting-at least it hasn't been raining here. Also can't use it when the clothes are on the line

Page 5 of this thread has the answer. The pipe finishes at a point which is around 50mm short of being level with the top of the funnel. Mine is slightly longer, finishing around 30mm short of the funnel. It doesn't seem to make much idfference, as long as it finishes close above the funnel somewhere. I'd start longer and cut it off a bit at a time once you are ready to test it out.

Cheers Sturdee, I spent a couple of hours of the weekend hacking into my Triton dust bucket with some trepidation. Your system went together surprisingly easy, and the difference is mind blowing. NO dust at all in the vaccuum bag. Waaaaay more suction. Thanks again!!

G'day All.
For the life of me, I cannot find the plan on the Triton website that you are all talking about.
I go to Sturdee's projects but nothing loads.
Can some one give me a link to the correct page?
Thanks.
Hooroo.
Regards, Trevor

I've just shortened the outlet pipe on mine. I'm not sure it has made a big difference. I still get very fine dust in the vacuum after a lot of use but I'm being pretty fussy, it's a great setup. I might cut some more off and see how it goes.
I also think that ledge on the inside of the bucket collects too much dust and I want to create something to make it sloping. It's going to be called the 'Gumby' mod to the 'Sturdee' mod. (how about that Pete ?) :eek:If at first you don't succeed, give something else a go. Life is far too short to waste time trying.

On friday whilst John and Janet were inspecting my shop we opened the vacuum cleaner to see how much sawdust had collected in the bag. We could find nothing and that was after vacuming about 50 litres of sawdust over the last 4 months since I last looked.
Gold leader you won't be disappointed with the mod. I have just got myself a new paint drum as I need to make another for my dedicated sanding station. They seem to multiply.
Gumby, go for it mate, all you need is a $ 2 gapfilling cartridge from Bunnings, a spatula and some artistic flair or maybe use some playdough.
Trevor, thanks for your comments about your difficulty in finding the details of the mod, bits are posted under various threads and in various locations. I'll try to find them all and create a new thread quoting all the references.
Meanwhile if you have difficulty in finding all let me know and I'll email them direct to you.
Peter.

I found my funnel at a 2 dollar shop. Well actually it was at Lane Cove, so it was $6.99. But the diameter was actually BIGGER than the Triton dust bucket, so some careful time at the bandsaw and sanding machine got the funnel in with a close interference fit. No ledge in my bucket!
And the paint drum was sourced of all places from bunnies. And it had never had paint in it, so was clean as new.
An 80mm (or thereabouts) Hole saw took care of mating holes through all the necessary components.
All in all a top mod, I'm blown away by how good it works, and how easy it was"I may be drunk, but you ma'am, are ugly. Tomorrow, I will be sober." Winston Churchill

Our local Mitre 10 (Wodonga) has 280mm diam funnels at the moment - on one of the "cheapies" tables that they put up now and then - maybe other Mitre 10s do the same? They are "Lion" brand and are selling for $5.95 but are probably out of the same factory in China that produced the 2 dollar shop ones.
Like Gold Leader's experience I found it was a simple job to take a bit off the top rim and get a good squeeze fit into the bottom of one of Bunnings' 20 litre buckets (as per Barry White's cyclone approach but with no ledge at the top to trap dust).
Works like a charm.

Fine dust getting through

Presumably every time you switch them on, there is a net movement of air up from the collection drum and cone towards the exhaust tube, as the presure inside the whole unit (drum, funnel, upper bucket) drops. Once it's running that's not a problem, but in the startup, possibly fine dust which is adhering to the surface of the funnel, and maybe from the collection drum, gets dislodged and sucked into the vacuum cleaner before the swirling action of the cyclone gets established. That might account for a lot of what's appearing in the bag.
Maybe Wayne or other cyclone gurus who know more about their behaviour could comment?
Cheers...Jeff.

Jeff,
You probably are correct with your deductions as to why some dust still gets through with the mini cyclones. This would also be true for the big cyclones as all that I have seen have a final filter attached to it.
However, the amount that gets through to the bag is so small that if you have to clean the bag once every six month of a little bit of dust, which hasn't caused any lack of suction, you have to be really fussy to worry about it.
Peter.

A few posts back, I said I'd cut the return pipe a bit shorter. I'm happy to report that there seems to be a noticable reduction in fine dust in my vacuum unit since I did that.
The pipe now comes down approx half way between the lid and the funnel. Evereything else is still fine so I'm sure it's an improvement on my setup. I wonder though, that we seem to get different reports about fine dust collection and i think it has to be due to the differences in each vacuum unit which does the sucking. mine is only a small machine and maybe something with a bit more grunt would reduce the dust even further - just a thought. (But I'm still very happy with it Pete ! Sure beats the original Triton setup.If at first you don't succeed, give something else a go. Life is far too short to waste time trying.

Sorry to revive this very old thread, but I have a question.
I have found a source for a 300mm diameter funnel, which will save me making my own cone. However, it's a pretty shallow funnel: it's about 170mm deep.
I think most of the cones I've seen in mini cyclones built by you fellas are a deeper V than that.
Do you think this will work?
