   If I understand your question, you are concerned that their will be too much "suck"?  IMO that won't be a problem.  I reduce down to 2" at my router, and the perceived suck is a bit more as with a larger orifice at say my table saw.

   OTH, I use a Fein shop vacuum with my orbital sander because I like powering my sander from the plug on the vacuum.  The vacuum turns on and off with the sander.  I use my slot jointer the same way.  In each case I use a short piece of rubber hose to adapt one fitting to another. Other shop vacuums have this switched power outlet feature also and it is real handy, especially when doing finish sanding in the house.

   Hope this is responsive to your question.

   Hi Brian.  I think it's the velocity that's of concern when reducing the diameter of the hose so much.  But I have a different question: Why use the DC for this purpose?  I use a small Shop Vac with my DeWalt ROS and it works great.  The only improvement I can imagine needing would be to go to a large vac; can't imagine needing to use a big dust collector.

   Forestgirl,

   Good point, the shop vac is probably more appropriate to this job but since I'm new to the dust collection club I want to hook everything to it possible. Also my Ridgid shopvac is SOOO noisey I almost like the whirrrr of the dust collector better. I'll just have to resort to the earmuffs.

   Thanks,

   Brian

   Brian, I know what you mean about the noisy vacuum!  Although I haven't done it yet, a good solution is to build a carpeted box for the vacuum to live in.  Also you can add a muffler. forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)Another proud member of the  "I Rocked With ToolDoc Club" .... :>)

   My small tool dust collection solution comes from being cheap and clumsy, and having a small cluttered shop.  It is to buy a few of those small 1-2 gallon shop vacs at garage/estate sales.  I have three so far, that I bought for $5-10 each.  THey are really handy to move around with you and your ROS or other small tool, easy to manage, and quieter than the  big shop vac or dust collector.  I have a portable dust collector, and a 16 gal shop vac in an insulated plywood cabinet, but they are a pain to move around and trip over the hoses.  THe small vac can go anywhere, sit on the bench where you're working, or wherever.

   Tried it with my 2hp DC and it just choked the DC to the point that top bag didn't inflate.  I suppose you could have an open branch and bleed enough air through a wastegate to get it to work.  Besides calling them DC's are kind of a misnomer.  They're really chip collectors.  I use my DC for machines and my Fein vac for portable tools.  Even though they're spendy, they're worth it.  I especially appreciate the 58 db sound pressure level compared to my old screamer ShopVac.

   We trained hard, but it seemed that every time we were beginning to form up into teams, we would be reorganized.  I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.

   who knows a little more than I do about the physics of vacuum presure..

   Just me.. I think in Space ya can get sucked out of a little hole in a space ship..

   Well, I saw it in a Movie so must be true...

   That being said you could probably setup a woodworking shop inside a spaceship and use the convinient vacum of space to your advantage.
