Hi Guys
After working few years in kitchen fitting and general building with using my dust extractor  GAS 35L 
I just get bored after loosed suction and full of dust disposable filter bags (they are not cheap).
I've strat using cyclone separator fitted to 10L paint can.
Working at customer permises this solution was not perfect due to 2 separate parts of dust extractor 
(not handy in limited space kichens) and wasn't look professional.  
I've seen few days ago that festool have integrated dust separating sytem and I've decide to build my one.
Propably I've spend similar amount of money for this project for developing it as much as Festool one.
As a Bosch tools user that was just matter of time to integarte that with my range of Bosch tools.
You can see on photos ready product.
There was few things to developed:
- sealing of l-boxx (using door seal glued to walls of box)
- flimsy walls after vacumm pressure they was bending and disconnecting seal in effect loosing suction 
following with reduced power of cyclone ( dust and debries gets to filter bags )
Now everything its working as should be.

Maybe that will be helpfoul for somebody.
Enjoy

Regards
Matthew

Hello Matthew.
Really like these sort of tool hacks. Good job mate. I like the simplicity of your solution. Even including the L-Boxx, hose, fittings and cyclone I'm pretty sure yours is far more cost effective than the Festool option, which here in the UK will cost £249+. 
I considered adding a cyclone seperator to my GAS 20 L. I was going to construct a cyclone between the motor (top) and the dust collector (bottom). I ended up turning the vac into a mobile workcenter instead ( SEE HERE) as that would do more to help my workflow.
I still plan to strip down a vac with power tool take off at some point, adding a cyclone seperator and packing it all in a couple of L-Boxx's. A project for next year I think.
Worth mentioning that Bosch's new (ish) GAS 18V-10L cordless vac uses cycplone technology. This makes it bagless and illiminates filter clogging. I'm sure I remember BOB/Bosch mentioning this will be incorporated into their new corded vac sometime in the future. 
All the best.

On attached photos you can see performance of dust colector.

There was heavy grinding of the old tile adhesive; preparation before self-leveling compound.

I used an angle grinder with a diameter of 7 "(180 mm diameter) with a dust shroud connected to the GAS 35L via a dust separator.
After completion of the work, about 60 kg of fine dust were collected by the separator and about 250 g. in a dust bag.

Hi MATTEWWBK im accumulating parts for this as like BAILEY ive been thinking of it for a while and ive got a couple of questions and hope you can answer  ? so here goes 
1/ the big one is what did you use for connecting the vac to your cyclone hose and by that  i mean did you buy another hose and cut off the ends !!?? OuCH ££££ or what or just cut up the one you had and ?? as i would still like the option of just the original set up as it goes on different jobs 
2/ how stable is the cyclone up there as its the one with the hose on it being pulled around 
3/ is there a need for such a large L-Boxx 0r could it be a 238 ?
4/ anything else youve found out in this build that you would change or are going to 

thanks malky
