Thien Baffle, first attempt failure?

[retired2]

*** months later for an update ***

Wow...  this Thein baffle has done EXACTLY what it was suppose to do.  Have emptied out the blue barrel 6 times after being near 85% or so full.  Just this weekend, I installed 2 Wynn Env 35a filters and 2 clear plastic bags for my dual bag dust collector.  Which gave me a reason to empty my 2 old 30 micron (or maybe 20 micron?) original bags, there was about 6 gallons of brown looking sugar... oh wait... I mean fine dust. 
What a great first wood working project.  Learned alot about do's and dont's here on the forum and abroad.

Retired2... yes, I eventually put 45-45 elbows at each bend for the feed into the impeller.  Had to move my Grizzly back a little bit more but that's ok.

Congratulations!  Looks like it is working great!  In your first post, you mentioned using a bell mouth.  I'm not sure I would recomment that.  I could not find the diameter of your separator, but it looks like it might be a little small for a 6" bell mouth.  Yes, it would fit, but the wide flange in a small chamber might actually contribute to waste by-pass.

and wouldn't you know it....   you could hear the knot of wood in the video that is rattling around in the tophat which did NOT hit the impeller :)
To date, I have not used a bellmouth.  I do not think I will have a need to, even if it helps 2-5% efficiency.   It works perfectly so do not want to jinx it.
