If it works, I like it.

Great, that should work better than reducing the diameter (area) of the pipe.

Only speaking off the top of my head but I would not reduce the diameter of the tube.  Instead I would try Making the end retangular so as to have the same area at the outlet.  Just shooting from the hip.  I made mine like your 1st picture cutting off the edge.  I would fefinitely like to see any results from testing on that idea.

X Ray, what was the final verdict on the HF DC?

Might, but still worth checking.  Or just call HF.

Could be a loose impeller on motor shaft.  Or call HF and ask if you can bring in just the blower unit for exchange.

Anxious to see the results of further testing.

It would be good to use with a shop vac, IMHO the diameter is too small to use 4" lines with it.

That is good to know.  Might try that on my little 1Hp DC for my down draft sanding table & router. :)

Is there an advantage to larger line after the separator, larger than the line between the blower and separator?

That is always good news!  :)

Possible the campground we are in is filtering them out????  Will try again when we get back home next week.  I just looked at a couple of older post & they don't have any pictures either.  So probably the network here in the state park.

I don't see any pictures?

1 1/2" or 2' placed as close to the outside edge as you can.  Only need 4" if using a DC with 4".  For a shop vac the smaller size is suitable. :)

That would be interesting to read. :)
