Increasing chip collection capacity

[Karl]

Hi all

Hope you can give me some advice.

I have an Axminster dust collector which I use for collecting the debris from my Makita thicknesser. I know it's the wrong machine for the job, but I don't have room for a proper chip collector. My model is similair to this.

What I want to know is this - is there an easy way of increasing the drum capacity of the machine? I know that Triton do a "dust bucket" which fits in-line between the dust producer and the extractor, and collects the larger chippings, but allows the finer dust to go through to the dust extractor. I'm thinking of something similair, but on a larger scale (a big black bin) to collect the chippings in. This will mean that the extractor will be emptied less frequently.

Is this a similair principle to a cyclone - about which I know nothing.

Any help appreciated.

Cheers

Karl

yes I think what you're asking for is a cyclone, of which I know little about.

However, I'm considering modifying my RSDE2 so that I can mount it on the wall and have a bag underneath that catches the dust\chips. This way I can just unclip it at chest level and carry the bag out to the wheelie bin. The bag will obviously bigger capacity than the current steel bin.

This is what you're after, Karl.

one of these http://www.axminster.co.uk/product-Axmi ... -21891.htm and a plastic dustbin - problem solved.

edit: lol - great minds roger....

Karl,

I think you are looking for something like this:

from Lee Valley, here, I am sure you could make one, maybe not quite as nice to look at but cheap and effective. :lol:

 

[DaveL]

Doh, beaten to it by BSM and his idea is in the UK. ](*,)
Must type faster.

1. Make a box out of ply, mine is 18 in square by workbench height as I also use it for a bench sander.
2. A simple door on front, no hinges as suction from extractor works fine.
3. Two round cut-outs , must be near top of box, one for hose from P/T and one to Extractor. I cut three, one blanked off, as always moving workshop around. 2 at rear and 1 on side.
4. Got 3 hose collars/connectors from Wickes for a couple of £.`s

Job done. Was going to use draught excluder on front, not needed.

My only issue with that system is that you have to have space for both drums. I thought about making a much smaller drum for the RSDE2 and cycloning it off. But by the time I've done that I might aswell just modify the drum of the RSDE2 to take a bag.

Thanks guys.

I have a spare black bin, so will make an MDF lid similair to the one in Rogers post. Will report back with results.

Tom - I know what you mean about size, but I have a space at the end of my workbench where both units could fit side by side. This way they wouldn't protrude above bench height, thereby impacting on the use of other machines etc.

Karl it will be much more effective if you can angle the dust inlet so that it comes in at an angle. Basically creating a very crude cyclone effect. Something like in Dave's pic.

 

[Karl]

Gotcha Tom - i'll do a trial piece tomorrow and see how it works.

Hi all

I got the unit put together today - the grab adhesive is setting as I type. Will post some results tomorrow once i've had a play.

Quick question though - the only 4" ducting I have is a piece of the expandable metal type. I (think) that I had read somewhere that this could be dangerous, and poses a fire risk due to the risk of sparks. Is this correct, or have I made it up?????

Cheers

I use the Camvac interceptor lid on a plastic water butt huge capacity sucks on to drum and seals really well hardly ever empty the plastic bag on the chip collector now

 

[Karl]

All hasn't turned out as I planned with this collector......

Example:

An 8" wide piece of oak which is to be thicknessed

With JUST the extractor connected and 3 passes through the thicknesser

A few chips escape from the front, but nothing too bad.

But put the extractor through the black bin set-up, and I end up with this at the rear of the extractor (again, after 3 passes)

I don't think enough of the extractors suck is getting through to the thicknesser when it's passed through the black bin collector. I suspect a few problems

1 The seal between the bin and MDF lid isn't great (draught excluder), but it does cause the bin to collapse in on itself if you block the pipe, so something must be working ok

2 The pipework running from collector to thicknesser is 2 1/2", but from extractor to collector is only 1 1/4".

The system does work (ie the bin collects the chips and minimal stuff goes through to the collector). It's just not as good as the extractor on its own.

Any suggestions on how to improve it?

Cheers

Karl

Couldn't you try using a 2 1/2" pipe instead of the smaller pipe?

Or bypass the collector and join the pipes together and see what happens. I suspect it's becuae you're going from thin pipe to thick pipe.

Can we see a pic of the vac to dustbin setup?

 

[Karl]

Tom - i'll get some pics posted up in the next few days - i've got no charger for the camera at the moment, and the batteries just gone flat.

Roger - i'll give it a try with the pipes connected up. You theory makes sense though.

Cheers

I was able to use my RSDE1 and my home made cyclone, on my 10" planer, using 2 1/2" pipe reduced down from 4" on the planer hood. Ok I'll admit that the extraction wasn't as good as it is now, with my 3hp monster, but i felt that the RSDE1 coped well, even with the slight loss of suction that comes when connected to the cyclone. If your losing suction then its possible that the separator is too big for your extractor?
