Thread: Triton Dust Extracter

I built two cyclones using big red funnels i found in Autopro, just had to sand a bit off the rims and they fitted very snugly down the buckets, with about 0.5mm lip, so not worth worrying about. saved the trouble of making a top disk etc. they work very well and the only time dust gets through to the vacuum is when they fill up and i havent noticed it yet

Thanks very much, fellas.

And you get a greeny for acknowledging the help you got. Too many don't do that so I'm spreading green love for those who do. And red splats for those who don't.

i second the motion, tried to give you a greenie for saying it too, Gumby but it wont let me yet

I always give thanks for advice received. Now, whenever I do, I'm going to feel like I'm fishing for greenies!

Fear not, in the art of greeny fishing, I have a diploma

Not like that at all, princhester, as far as im concerned i like to reward good advice and niceness. too many members like to reward people for jokes etc, but its a woodwork forum, not a manners forum or a jokes forum..................ummmmm

Hi All,
Sorry to keep this ancient thread going, but I came across something cool.
I've been using my version of the mini-cyclone for a while, but it hasn't been perfect, since there is always a small amount of dust that gets into the vac bag. I've read with envy all those people who reckon they don't get any dust at all.

So anyway, this thread inspired me to try again and get it working as good as I could. So I was re-reading all the posts by Sturdee, and Wayne Davy, and finally re-reading Bill Pentz's website, to see where I could make improvements.

On Bill's site, there was a link to an American company that licences Bill's designs to make cyclones out of clear plastic, which is kind of cool because you can see how it all works. The website contains some videos of these see-through cyclones in action, so I thought people would be interested. Below is the link.

I am about to build a mini cyclone. When I look at the site above it appears that the funnel sides are much steeper. They mention a ratio of 1:64 for the ideal funnel shape that I don't quiet understand.

Watching the videos it would seem that the steepness allows the dust to circulate around the funnel more times, increasing its speed? and thus ensuring more goes into the bin??? Is this correct?

If I make the funnel with steep sides (say going from 130 that has been suggested to 230) and a shorter centre pipe - (say about 150 long as opposed to 230 internal length) does anyone with a greater knowledge of physics know what will happen? (I can easily establish a cutting diagram using some thick paper for the funnel shape and then use plastic etc to make up).

Also is there any relationship between the pipe whole size and the end funnel shape? I note 80mm has been suggested but most professional units seem to use a smaller outlet whole??????

I have a Triton bucket I could cut up but I also found thrown out a very nice bucket from a home brewery shop that once stored bourbon according to the lable. This would mean the exhaust smell would be nice and melow. This could easily be mounted on paint tin, but I do take the point about the strength of the Triton lid.

Thoughts?

Use the Triton dust bucket and follow my instructions to convert same into the Sturdee mini cyclone. It works as hundreds of users can tell you.

Bill Pentz site refers to the proper full scale cyclone powered with a 3hp motor and fixed ducting.

Obviously his ideal measurements can be scaled down to a mini cyclone size and may work better but you will have to do the configerations and calculations yourself.

How did you go on this? I always get a small amount of dust into the vac, particularly very fine dust. Did you find any effective tweaks?

i don't think it's worth spending too much time on it. Mine gets a small amount of fine dust in the vac filter but tappinjg it out every now and again is nothing copmpared to what I had to do before this modification was made. I think you'll always get some fine dust in the vac no matter what you do.

Ambers
My design previously posted may be of help to you as the funnel has been made to suit the diameter of the bucket.

I can provide the maths for the funnel design if required (thanks to Zenwood).

I have set-up the lid with 25mm conduit and was able to make all the connections without drilling the lid. The key was to sand the outside of the joiner on my table sander so it fitted the current hole diameter of the Triton lid. That meant I could continue to use the exisiting Triton hose connections without any alteration. Also, by using a T jointer and some careful shaping I was able to connect both inlet hoses and the free end of the T became the angle for the cycloinc effect (I haven't tested it yet though.
