I don't know what a bill pentz cyclone is, but I've seen offerings for 3 Oneida Dust Deputy products (or at least there were 3 different names) for use with Festool CT vacs.  From the pictures, they all look the same, and I haven't found anything comparing them.  The 3 product names are:

* Dust Extractor for Festool Vacuums.
* Ultimate Dust Deputy.
* Ultimate Dust Deputy II.

Does anyone know what the differences, if any, are between these?  Thanks.

The Ultimate Dust Deputy is on its second iteration already ? I thought it just came out a few months ago.  Does anyone know what the difference is ?

I have an UDD, I presume the first iteration since the Oneida website suggested it was a new product when I got it (free with my Oneida cyclone).  It works, but I find it to be very unwieldy on top of my CT-33.  It just seems like you have a lot more hose sticking around, and some of it projects out the front of the vac.  I think there's only two extra lengths of hose, one connecting the vac to the CT, and one to provide suction to the bag, but it seems like more.

If you want to know about Bill Pentz and his cyclone info, go here:
BillPentz.com :: Dust Collection Research

Lots of info. He's been a proponent of better dust collection for all woodworkers for a long time.

Hey Alan, sorry for the confusion but that link was not directed at you. Obviously you would know about Bill Pentz but as lawhoo pointed out, he does not.

 

I have both a mini Pentz cyclone and a Dust Deputy.  The cyclone is hooked to my Rigid shopvac and handles my planer, router table, and shop cleanup.  The DD is on my CT22, which gets more use as it has the hoses that fit my Festools.  I can't really say which is more efficient, the cyclone is a bit less top heavy and is on top a metal trashcan so I don't have to change it as often.  My DD is mounted to a 5gal bucket which is really less than ideal as it fills up much to quickly with heavy cutting or routering.  For sanding the 5gal will last a while between changes.  Emptying the plastic bucket is a messy job as the dust sticks to everything.

The Pentz cyclone only took a bit more time to build than modifying a stock Dust Deputy.  You need to build a plywood lid stiffener to keep the lid from imploding, and build a plywood template if you want to mount it to the top of your CT.  Knowing what I do now I would probably spring for the new Ultimate Dust Deputy, or buy a metal one and put it on a large fiber drum so I didn't have to hassle with it as often. 

 I got my plans from Bill's site, but also got some pictures from Sawmill Creek as well.  I never bothered to check it's efficiency, but I have not changed the bag on my Rigid in over a year so I guess it's working pretty well.  I am using a 10 gal metal trashcan for the collector, but if yours is going to be stationary I would go bigger. 

I took some pics but can't find my card reader, I will try to upload them tomorrow.

to buy it in the uk would probably cost me around 200 euros plus their cost of shipping from the states plus shipping to ireland plus vat plut costums charges. i could make one for 50 euro and invest the difference in something else that might make me money

i have done a bit of research on the thein and found that they are no good for fine dust as you would need it to be massive to work . they also suck up the dust when they get half way full. a cyclone is the only way to go


any body got any ideas on where to get a dyson cyclone . i could buy one but they are very dear. i tried my 3 local electrical shops for a broken one and my local recycling center. all atemps have failed. where else should i look

A very interesting idea, but the Dyson vacs I´ve seen, all seem to be multi-cyclones, consisting of a couple of smalle cyclones, working in unison. Wouldn't these cyclones be easily clogged by wood shavings?
Or is there perhaps a "first stage" cyclone to separate the course dust ( like planer shavings ) before it gets to the small ones ?

I've been trying to decide about a cyclone solution.
It looks to me that the cyclones' basic design alone does a pretty good job.  This cyclone build basically out of garbage

seems to work pretty well.  I got to believe precision improves performance, but just anything in this direction helps.

Anyone have experience in performance between a cyclone and dust collection separators of this style?

i cutt all the parts and bent them to shape . i need a welder to weld them together. a local shop wanted half the price of a new welder to do it for me so decided to buy 1. i am going to get an inverter mig welder as i have a stick welder already. unfortunitly i havnt got the money yet.
as for the cyclone for the vac . i put that on hold for now until i make my shop bigger . might make it for the midi i will get some day for site work. my ct22 has a homemade workcenter on top so space is limited.

i built a thein baffel out of a drum as a seperator. i heard a lot of good and bad ( not as effiecient as a cyclone ) things about it and decided it to build it as any thing is better than nothing.  only used it a small bit and so far im getting 95-100% in the drum of table saw chips. i will start a thread on this

can we see some pics of your cyclone

i have a 50mm hose in and a 27 or 36 out of mine. i get great suction from both

Ed Morgano made one for a while before he sold the Clearvue business.  There was a legal issue related to it and another similar mini cyclone (Dust Deputy?)
