SVAR -
Thx for reading/commenting on my post. FYI... I think that you missed my point.
You apparently didn’t read (or understand) the next sentence.
Having an ALL STEEL Dust Deputy/Drum setup has NEVER been about DURABILITY.
At my age - Both plastic or steel/metal - And my life insurance - Have greater longevity.[wink]
I read the multitude of FOG posts about plastic Dust Deputies - And the travails of “fried” Festool Dust Extractors.

You are wrong. The latest plastic Dust Deputy cyclone is CONDUCTIVE. Designed specifically for CTs.

Yep, I was just about to reply to Joe's post on this. It took Oneida a long, long time to finally make a DD from a material that was conductive enough to eliminate the static discharge issue on CT extractors. So, now their newer black plastic DD will work as needed. And their newer UDD with the black plastic cyclone is going to be a better solution than trying to mount a steel drum and steel cyclone on top of your CT. Just too bad it took Oneida so very long to correct their product -- especially when they were told of both the situation and the solution here repeatedly.
Looks like your rabbit joint is a hare off! ;)

I made my own cyclone in a Sys5. The cyclone itself, an anti static Dust Commander, along with the plywood lid, inverts and fits inside the Sys5 and then packs away.
Brilliant!

Very clever idea.  Cyclones require tight seals between the cyclone and collector bin to be effective.  Can you share what you used?

Thx for the info/correction. Accepted.
Glad it works for you.[smile]
All the same, I’ll stick with my setup. Works for me.[wink]

I’m curious how the liner stays in place without that little vacuum hose that the Oneida DD includes; the one that creates negative pressure on the backside of the bag.

Would have thought that’s something Festool would have done.   

Does the shorter hose fit inside the sys 5 aswell when the cyclone is inverted?

Just a simple and safe way transporting the cyclone in one hand cyclone  sys5 with short hose inside  and your other hand Festool vac with long hose in hose carriage which could have sanded attached so you could carry tool vac and cyclone all in one trip.

Then you have festools setup 😂😂🤣 gotta do atleast double the amount of trips or more.

  • Does Anyone Know What Time It Is?
 @Distinctive Interiors

Thats a pretty slick set up. Please provide more info. How effectively does  it collects dust etc.

 Im interested in building something like that as Im started to do some on site work and Im tired of emptying the CT bags .

Anything to save a few quid and make life easier is always a good thing.

I got the idea to make it from a similar set up someone on here came up with a few years ago.

I tend to use 36mm A/S hoses for the majority of my cutting and routing, so there is not enough room inside the Sys5 for a short hose and the inverted Cyclone.

The 18mm plywood drop box is screwed and glued together and all joints sealed with Silicone sealant. The plywood top is a relatively snug fit in the rebate and although not a perfectly airtight seal, the drop box seems to work pretty well. I use mine mostly out on job sites and have had a lot of positive comments from other trades and clients.

The inlet and outlet pipes on the Cyclone don't fit the Festool hose ends. The spigots are slightly too small, so I bought 2 Festool 50mm straight couplings and wrapped the Cyclone spigots with aluminium conductive tape tò ensure I had electrical conductivity.

Overall, the set up suits my work method and I am happy with its efficiency.

The seal of the collector box is very important to the effectiveness as even small leaks will massively reduce the separation, starting with the finest fraction. In case you get too much fine dust in the CT bag it might be worth to look at the seam between box and top, adding a rubber or foam seal there should help you get rid of any remaining leaks.

When I first saw the one image of just the product (last week? Monday?), I laughed at it.   
Now that I've seen the set of marketing photos demonstrating onsite use... ok, now I get it.   

Whether it's a good product or not is something we'll have to wait and see.
However, based on looks, if I was sanding drywall all day (or doing concrete), this is totally better than the other options out there.

Just swap dust bins everytime you fill up.  At the end of the day, tie the bags up, lift the bin (the one that says Festool) over the bin (the one that says "Waste") let gravity do the job; no plumes and no dead back from lifting a bag. 

I used to hand schlep bags of instant concrete by the trailer load, and soil, and waste bags filled with offcuts and other misc garbage... I get this product.  I get it a lot.   [big grin]

For concrete and drywall, just imagine how much nicer this is than option a.   
And yes, the concrete industry is buying Festool dust extractors.   So, I don't see this as a Dust Deputy replacement.  I see this
as them seeing where the dust collectors have been getting sold and addressing that market's needs.

The chief value of the new Festool semi-cyclone separator is that it is more mobile than most and is the only one that allows you to stack stuff on top.

And that’s i ruggedly portable (at least as rugged as a systainer).  A DD wouldn’t live through daily transport and in/out of the truck for the working man.

I made my own cyclone in a Sys5. The cyclone itself, an anti static Dust Commander, along with the plywood lid, inverts and fits inside the Sys5 and then packs away.

UNLESS you did something like this.  A very brilliant idea sir!!  I’ve had some thoughts about making a cyclone in a systainer but got hung up on how to collect.  I was thinking of stacking two systainers on top of each other - top is the cyclone, bottom was the collector.  Your idea is way better.

Thanks!......But as I said in an earlier thread, I can't take the credit for the original idea. I just developed the idea based on someone else's Cyclone Systainer. It did however, make sense to invert the Cyclone and store it inside the ply drop box when not in use, due to its odd shape.

Regards, Tim.

Yeah, inverting the cyclone for storage is the slick part.  [emoji41]

Now I’m wondering is the hose length will work with a CT Clone stacked on top of a CT SYS.  If it could, then the CT SYS could play a much bigger role in my workflow while never leaving the Sys Port.

Edit:  after looking at the CT SYS, I don’t think it will work.  The CT SYS only has a big enough hole for a hose to leave its Systainer housing.  No room to get the hose in from the SYS Cyclone.

I was thinking along these same lines. Wondering if the separator will work with th CT SYS?  Will definitely cut down on how often I have to empty it. Was going to wait for my local dealer to have one on display so I can play around with them.

I don't get it. You only need one hose that pulls air from cyclone into the CT. What's the problem?

Anyway, I always said the whole vac system has to be modular in sys sized blocks. You buy one motor (sys2), then snap in dust bag compartment of your choice (sys 1 through 5). Than you could have cyclone section in between designed to avoid external connecting hose. All goes on sys cart. Easy to reconfigure for the job at hand.

You’re right, one hose not two.
