J. Phil Thien's Projects

I have recently bought the HF 2 HP dust collector to upgrade from their 1 HP model.  I am in the process of setting it up and I was wondering since I am upsizing all my duct to 6", would it be beneficial or neccesary to upsize the blower exhaust to the filter/bag assembley?  I don't know if that 5" there would restrict my cfm any.  Thanks a lot Phil.  This is an outstanding website you have and I truly appreciate what all you do for your fellow woodworkers.

  I just bought a HF 2HP unit.  I am using 6" SDR PVC duct.  My question is, does the 5" running from the blower to the filter/bag assembly affect the cfm enough to upsize it too.  Since I'm at the beginning, I would rather do everything possible to ensure the best possible performance.  I also have all my tools on one wall initially due to the layout of my shop.  I've realized in this process however that this should make dust collection simpler.  I have my RAS, SMS, DP, BS, and BS all within 18' on the north wall with the TS and Jointer protruding perpendiclarly 8'.  Is it worth cutting out the fittings to upsize them to 6" on the blower to filter/bag junction?
