   Gordy,

   I think you'll generally find that this will not work. Dust collection systems work on the principle of moving very high volumes of air at relatively low pressure. Vacuums are the opposite. For example, if you put a small vacuum hose on your dust collection and expected it to work like a vacuum hose you'd be dissappointed. Moving wood chips is rather different than pulling dirt from carpet and upholstry.

   I suggest looking at some of the manufacturers' websites that may detail how DC systems work. Try http://www.oneida-air.com for starters.

   Best,

   Seth

   Seth,

   Thanks for your response.  I understand what you say and I agree with the analogy of connecting a standard vacuum to a table saw, it wouldn't work.  What I don't understand, is a dust extractor generally operates with 4 - 6 inch ducting which gives you the high volume / low pressure.  What I was wondering is that if you reduce the ducting to 2 inch, will this increase the pressure (and reduce the volume).  Logic tells me that it would.  With an additional vent somewhere in the system so as not to over tax the motor I cannot understand why this would not work.  I checked the web site you suggested but there is nothing there on what I am proposing.  I guess there must be some other reason why this would not work because someone would have done it already if it did.  Maybe the dust extractor companies should think about a dual system.  I couldn't be bothered fitting a ducted vacuume system to the house, but my motivation to buy one would change if I could use it as a dust extractor in the shed as well.

   Regards, Gordon.
