Found a couple of YT videos of blokes making them, but the plans are no longer available.. I'm figuring that the dimensions of the cone are pretty important, so I'm keen to get any help/plans I can...

Anyone got something they're willing to share?

Thanks

I do not understand what you mean by 4" but Bill Pentz site has all the information and plans to build cyclones that you will need.

Thanks for that info, I'll look it up...

I can buy a 50mm inlet/outlet version for about 50 bucks, no brainer. I'm looking for 4" inlet/outlet...

PM Aldav. I’m reasonably sure he sells such a unit

I don't normally advocate their use as all of these cyclones place a significant restriction on airflow when used with a standard DC but here's a 125/150 mm inlet outlet for $100 including delivery.

It's "supposedly" designed for 300 m^3/hr which equals 175 CFM which is about half the max flow 4" ducting can achieve using a standard DC.
It will almost certainly carry more air than this but probably won't be as quite as efficient at separating fine dust but it shouldn't be any worse than the 50 mm inlet/outlet versions.

What are you attaching it to?

More like $180 AUS. It’s $134 US with shipping.

Whoops - was looking at the smaller ones that showed up as free shipping.

Thanks, and what are you trying to achieve in terms of dust control?

So off the collector I have a Y connection and two blast gates connectted to that. Then a short hose to sliding table saw and the other a length of hose with a quick connect which I connect to whatever is in use, mitre saw, bandsaw, Router table, jointer etc. You get the picture. So far this all works fine, apart from the mitre saw..?? Another day for that. What I'm trying to do is make it easier (and cheaper) than changing the bags...

Hi David

I have the set up you are aiming to build, with the exception that I use 5" hoses throughout. This noticeably improved the collection of debris.

This is far from being my final system. It is just an interim until I modify the outlets in my machines to take 6" hoses. Emphasise interim system. As it stands, the system has good chip control. I cannot speak to the dust control without taking readings. The cyclone works well.

Here are some pictures that may be helpful ...



The little dust at the bottom of the bag was there prior to the cyclone being installed.



I built a gate system to connect the combo thicknesser-jointer, bandsaw, and tablesaw to the DC ...



This is the construction I came up with. It works surpringly well ...

Hey Derek,
Nice work...really nice.

The wife and I are now doing markets monthly with quite surprising sales figures, which means I need to get dust and chip under control more. Once upon a time I'd easliy spend 1/3 of my time in the shed sweeping and vacuuming. Now I resent that as I could be using the time to make stuff.

So my Q would be where did you get the 5" cyclone from?

I'm happy to connect each machine up as I use but the 3into1 idea that's gold...
