New from Festool for Europe - September 2018: CT pre separator with cyclone tech
- Thread starter six-point socket II
- Start date
I like the idea of the Festool cyclone, except for the small capacity of the bin. With a thicknesser that would fill up in minutes.
I plan making a cyclone to fit on top of a 240 litre "wheelie bin", using a cut-down road cone as the centre.
Has anyone else attempted this, and if so, with what success?

I would wonder if you couldn't skip the bag altogether. You'd have to be careful you don't clog your filter by overloading the bin, but I bet you'd offset your loss in suction.Roachmill said:

Well after two weeks of use I find the CT cyclone drops suction so much that my small workshop is starting to fill with dust that was not noticeable before. Tried new bags and bigger hoses. First festool product that I regret buying. My 15 euro chinese dust commander performs much better than the CT-VA.

What I'm actually wondering is if you could skip the bag in the DC, though. People report so little dust coming through the pre-separators that leaving out the bag may help recover some suction/static pressureScorpion said:
I'm not surprised at the comments here - early on it was clear this was a fancy thien separator, which have always been said to create a big SP loss compared to a cyclone.

Skipping the bag all together would ruin the expensive HEPA in short order. Personally, I wouldn't even try it.

Two weeks in running this thing through the daily grind and OHMYGAWD it's amazing. Just cannot believe how well this thing works for being shoved into a systainer form factor. I've run it through sanding workflows, planers (DW735X w/helical blade), jointing, Kapex-ing and all sorts of jigsaw and router tasks, as well as overall shop cleanup, and it really is at least just as good as the dust deputy was in performance and suction, but then of course, it's so much better in form factor and practicality. The clear bin is really invaluable too. With the DD, I'd lose track during a long planing session and then have an oh-crap moment when I finally remembered that I'm probably starting to overflow into the CT bag. It's been great watching the bin slowly fill and then empty before accidentally running it over into the CT. Overall 10/10 would recommend.
I wonder why the Oneida couldn’t be manufactured with a clear bin? As long as the cyclone is conductive the ground path is maintained, so what purpose does the conductive bucket have (other than obscuring the one thing you need to know...is it full yet)?
Wood whisperer did a test on YouTube and verified my findings - 30% loss in suction how I’m configured. Apparently I’m fairly accurate at had suction guesstimating. [emoji41]
After using it for a while I’d say that for some tasks (ones where the collector had maybe more suction than necessary where a reduction isn’t impactful like sanding, where I previously had to turn down the suck of the collector anyway) it works well. In other cases, where collection was previously barely acceptable (like kapex), the collector just reduces the suction to the point where it can’t capture enough now to be deemed acceptable.
I do not have many tools that create big chips. I do have a router but haven’t tried it yet. I suspect it will shine there if it has enough suction to pull all the chips from the work field.

It could, however I think the issue then becomes the price of the conductive injection moldable materials. Plastics loaded with carbon black are pretty cheap compared to materials loaded with chopped stainless fibers. It’s probably just a cost thing. Imagine the outrage if Oneida sold their clear product at Festool prices. My God...the earth would pivot on it’s axis. [big grin]
I just got my separator a couple of weeks ago and have emptied the container 6 times. Drop of suction is most noticeable when vacuuming a big mess on the shop floor. Sanding, TS 55, Domino, router, 16" drum sander my CT 22 seems to have a enough power to compensated. The separator does not work on Kapex, 30% reduction of suction power is to much for it..
My favorite one is vacuuming the wood stove and Green Egg, now it has become a 5 mn job and no vacuum bag $$ wasted. Overall a very good buy and will now purchase a new CT36 instead of a 48. Both vacuum have the same mother and with the cyclone I do not need the larger bag capacity as the cyclone can be emptied in 2 mn and save $$ on bags .
