J. Phil Thien's Projects

I dont know if you should or not...but like I said, it seems that a bit of experimenting has really helped out where some have said it would not.  It may be that if you have the baffle in both, it might filter out even more of the larger particles and keep the filter that much cleaner.  Who knows till you try it.

dbhost, I have read a few threads now on the Harbor Freight DC that said not to put the neutral vane in...I did anyway (same design as Vaughn's).  I have tried it both ways and it does seem to function much better with the neutral vane in, rather than out.  This makes more sense to me anyway because it more closely follows the original design.  With the neutral vane in, I am getting a much greater and more concentrated cyclonic action in the collection bag.  I may make another baffle and try to reposition it without the neutral vane to see how that works in the future.  I wish I had the space though to use a seperator such as your doing...but this will do for now.

So as you and I are seeing, it is much better to experiment.  ;D

Still an excellent design though and so inexpensive.

I would really like to know how the baffle works if you rotate it a bit and go without a neutral vane.  I wonder how that would affect efficiency.
