DIY Dust Separator and Festool Hose Use - Help!
« on: January 11, 2018, 05:41 PM »
Hello, 

Relatively new to Festool, but in fairly short order, purchased the following in this order:  Carvex PS 420 EBQ (new), OF 1400 (used), ETS 150 (new), CT SYS (used), ETS EC 150/3 (new).  Started out because my Ridgid jig saw died on me.  I also recently built a Paulk style work bench that sits atop systainer storing cabinets on retractable wheels.  Still have to put the 20 mm holes in but will get there.

I am just a hobbyist but build things for friends and family and for fun.  I have not justified but only rationalized these purchases!

For me, the biggest benefit is dust extraction as I work in my garage only. 

I would like to build a box style dust separator.  Simply, the air cycles through and drops into a bottom releasing rectangular container - similar to how a Dyson vacuum dumps its collected load.  At least this is how I am currently envisioning the design.  What I have been struggling with is how hose and hose fittings would work out and all the info is unclear and multiple trips to lowes and HD with a extra 27 mm fitting indicates that very little fits nicely.

I am currently thinking of the following.  Use a shortened length of hose connecting the vac's input to the output side of the box using the standard fitting (it may be more universal per what I have read here an elsewhere).  If that works with a 36 mm hose, then I think my problems are solved. 

Purchase 36mm hose.  Cut short length.  Attach two right angle adapters to connect to vac and output side.  Use the straight hose adapter (that presumably comes with the hose) to the remaining 36mm hose to connect to the input side of the box with the standard 36mm hose end on the other end of the hose.  Then, I put the already owned second 27mm hose end to the other end of the 27 mm hose that came with the CT SYS.  I can then attach the original hose onto the somewhat shortened 36 hose or directly use the 36 hose with the 1400 (and eventually a TS55).

Any input would be greatly helpful prior to purchasing all this stuff AND if anyone knows of PVC or other parts that would easily work with the standard hose adapters that would be used as connectors on the dust separator.

If anyone has written about or already done this, please feel free to direct me as I could not locate it on this forum OR online anywhere.  Whatever I finish, if successful, will be posted with photos (no judgement on my low-end flintstone level work, please).

Hi Dana,

Have you looked at the Dust Deputy from Oneida?  I have their Ultimate Dust Deputy which fits nicely atop my CT26.  It came with the short hose and all required fittings.

Sorry if I've misunderstood your quest.
Cheers,

Barney,

Thanks for the thoughts.  I own a CT SYS so I am not on wheels and lugging around the DD / UDD would be a chore.  Attached is a conceptual drawing:

I'm not sure if the CT-sys is the vacuum of choice here.
It's more intended as a small portable vacuum for a sander or something similar with fairly small debris (read dust only).
The dust bag is small and will fill up quickly.
Sure when you use the dust deputy it's intended to have no chips in there, but I'm not sure this will never happen.
Further I have my doubts about long time running of the CT-sys.

I have the CT-sys solely for small on site jobs.
My shop has a CT22 and CT26 and the make long hours without any problems

Hi,

I'm thinking just the same, found couple of solutions. Maybe in your (our) situation CT SYS is enough if making that bigger dust bin.

Systainer in CT SYS should have open bottom, cut away bottom of dust bin as well. Then you have big hole straight from CT SYS original inlet to newly made bigger dust bin. Just seal CT SYS to your dust bin very well, there is no room for air leaks.
I thought some kind of a baffle to guide debris to bin. This means that filter don't get clogged so easily.

In other words, you replace that small dust bag with bigger dust bin.

In youtube you find some videos of CT SYS. At least Dave Stanton has one, where you can see separate original bin holding bag. If I remember correct, video shows that hole in systainer.

This idea was somebody else's originally. Found it here.

I bought and still use for my drill press, Rocklers Dust Right® Dust Separator
Item #: 45556  version of a cyclone.  It is cheap and works ok, not nearly as good as the three steel Oneidas that I bought later but it does the job.

rst - I also owned a Rockler Dust Right at one point but I ditched it because working in my garage, I simply do not have the room.  But it did work fine.  That is why I think I can somewhat replicate the idea using a smaller wooden box for which I have a space underneath the workbench I just finished.  I simply need help with the fittings.

VesaS - I never even considered what you (or someone) is proposing.  I would probably not as I do not want to "ruin" the CT SYS.  The box I propose would have a recessed handle in the top and a bottom opening so that when ready to dump, I would disconnect the hoses and pull it out, hold it above the trash (after taking any dust that I use for filler) and pull a catch. 

NL-mikkla - I don't dispute that the CT SYS is the bottom of the Festool Dust Extraction barrel, but that is not the point.  Trying to understand how the fittings would work before paying for a shite-load of hoses and fittings.

Thanks all.  Hope to hear some more ideas.  I was fussing some more with it in my head and confirmed that I will eventually need a 36mm tool end and so may go original 27mm with a 36mm detachable adapter at business end. 

Is there a right angle fitting that attaches to a 36mm hose?  Of course there is one for the 27mm.. The fittings on the box would be the standard opening that the hose attaches to...

The fittings that Festool offers to accept a hose is their Antistatic Connector Sleeve. I've taken one of there fittings and cut it in half and used each half on the input and output ends of my cyclone to make it plug-n-play. You may choose to get two instead such that you can attach 90 degree fittings inside the dust box. You could use something like a ShopVac Hose Coupling instead if you don't require the antistatic aspect -- the Festool and ShopVac vacs have similar sized inlets.

I've never seen where Festool has offered a larger 90 degree fitting. However, there are a number of 2-1/2 inch Elbow Fittings available that will connect to one of the hose connectors/couplers above.

Oke but my point is, the fear that you are investing a stuff load is hoses and coupling and quickly going to ruin/burn your CT sys leaving you with nothing but useless new stuff. You are free to endevour any way you want offcourse.

If you need a lot of hoses and coupling be sure to check out the Stihl vacuum assortment. Unknown to the big public (imo) is that they have a broad line of anti static adapters and hoses at a fraction of the festool price.
You can even order the hoses per meter, not sure where you are from and if that is the case with you but it’s worth to check it out.

NL-mikkla - thank you again for your time.  If it burns up, then I will end up buying something to replace it, but would still end up using a dust separator such as what I am building.  So, nothing to lose - would still need the hose and fittings.  But again, thank you for taking the time to provide your thoughts.

Corwin - thank you.  To confirm (hopefully you have the time), the couplers you linked to will fit the Festool hose end that connects to the CT?  So I am now envisioning each port in the separator equipped with the Antistatic Connector Sleeve so that any festool hose can be inserted while inside th box, the same ASC is attached to one of the linked elbows. 

Again, thanks all.

I fail to see where adding a separator will quickly ruin or burn a CT SYS -- this is just wrong as far as I am concerned. The addition will reduce the air flow, but, as I see it, will not cause any harm to a vac. It is not as if you will operate the vac with the suction blocked off.

The one thing to consider is static buildup which could then zap the circuit board on the vac. If you are worried about this, then either have a complete path to ground using antistatic fittings and hoses, or, just ground your separator.

Most vacs have an input that is similar to the ShopVac's 2-1/2" (tapered) port. So, yes, those fittings will work.

If you use antistatic connectors and hoses, then you can use a wire to connect the input and output on the inside of your box. This would allow you to use non-antistatic 90 degree fittings on the inside of the box.

You might consider a viewing window to see the level of dust in your separator.

Corwin - thank you again.  Just what I was considering - a copper wire that connects the AS Festool connectors inside the box.  I ordered one of arch to test before full dive and determine how to attach the ASC itself to the box. 

And yes, I was going to either full window or at least cut a slot and epoxy plexi glass on the inside to provide a fill window.

I will post any pics of finished project.

Update:

Purchased the following:

Festool 493047 Hose Sleeve, Antistatic Connector Sleeve

POWERTEC 70178 Elbow, 2-1/2"

Results:  The vacuum side of 27mm hose with he right angle connector (comes with CT SYS) inserts nicely into the Festool Hose sleeve.  It does not fit thee Powertec elbow.

Will update at next successful or unsuccessful juncture.

I mounted my "vintage" Shop Vac on top of the Rockler Dust Rite to save on floor space. Used two plywood discs and dowel risers (height to allow the hose ends to attach/disconnect from the Dust Rite), wound up having to use a Fernco coupling at the vac inlet. Even with the height, it's pretty stable and not at all tippy, follows along with a pull on the hose.

Instead of that I would suggest to get 'adapter hose #499196', contains the sleeve but also a 50cm D35 hose with 50mm rotating connectors on both ends - and isn't that much more expensive (at least where I live).
