My 2010 Dust Collection Video

[airnocker]

Recently DH42 shared his photos of his dust collection system after I had alluded to the one I use that is based on Oneida's Dust Deputy.
I know I've posted my YouTube video of this on other CNC forums but don't remember if I did so here.

I still use it today and the only thing that has changed is to a far more quite, but strong, vacuum source which is an old Nilfisk GS90 home vacuum cleaner.  In the video you can just see a corner of my first DIY CNC machine that used a Dremel Tool as the router.

Here is the video:  https://www.youtube.com/watch?v=5D796aO5HCo

Hello

You have no safety valve in case it clog ?





On mine there is no valve too and the MDF cover is beginning tearing (the container is a steel motor oil barrel strong enough and can't crush itself)

That's great, we are both Deputized.

No, no safety valve on mine and it has never clogged.  The sides of the Lowe's 5 gallon plastic collection bucket have sucked in on a side under heavy loads occasionally but only for a short time.  Now we know the likely reason for mine not clogging...because my feed rates are so SLOW and DOCs so SHALLOW!

It's not mine, I use a Thien system

Oh my, maybe that's why yours clogs.

Here's a YouTube video comparing the Thien Baffle vs. Dust Deputy cyclone separator efficiencies.

No, it's because the maple sycamore make very long "wires" and shards that can clog even my Ø100 vacuum tube ; the problem is the same with or without a Thien/Cyclone ... in fact, in my case, the goal of the external barrel is to have a larger capacity of chips, not to filter small dusts ; when I was cutting this parts, I was filling three barrels a day (180L) ... with a 8mm tool LOL (and the Festool tank is only 17L) ... there was very few small dusts in the Festool tank even after days of machining, so the Thien is very efficient too.
