J. Phil Thien's Projects

Thanks for all the help

Hello, I am new to dc.  I decided to build a Thien baffle because it looked easy and it would not break the bank.  I am starting on the woodwork on a remodel, and thought it would help keep the dust down.  I tested it and I'm not sure its performing as well as it should.  I sucked up about a 1/4 full of a 5 gallon bucket and ended up with maybe a little over a cup of fine dust in the filter.

My first question is do I have the elbow placed correctly over the 120 degree Section?
My next question is how far should the center pipe go into the baffle?
My last question is how can I tune it to Perform better?


Thanks for any help that you might be ableto give me!
