Hi,
I just setup my new 3HP dust collector outside my shop, and ran 6 inch stove pipe, (24 gauge steel) into my shop. now I need to either reduce that pipe to 4 inch and run standard hose and other standard adapters etc for my individual machines or run a 6 inch hose, and then reduce. My intent is not to have a multi machine setup. Just to have one flexible hose which I will attache to each machine as required with appropriate adapters. I’m not sure whether to have 6 inch or 4 inch flexible hose??
Either way I am having trouble locating a 6 to single 4 inch adapter.
Anyone got any ideas??
Thanks Guys (and gals)

Bill, how long will the flexible hose be?
Probably about 8 feet, the shop is only 16 ft long and the pipe is presently positioned about halfway. machines will generally be moved to the center for use then moved back.Thanks to everyone for the tips so far.

That's not too bad, 8'. The flexible plastic hose decreases airflow by quite a bit. Based on my limited experience, I'm thinking 8' to your table saw could hamper your dust collection at that particular tool. If there's any way you could have a shorter flex-hose to that, it'd be a good move, IMHO, or even run the 6" diameter stuff to it.
There's an on-line FWW article that relates to this, I'll see if I can find it.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

Go for the 6" and reduce at your machines. I made all the reducers for my shop with a heat gun and plastic drain pipe. Heat up the pipe and force it over a former to expand, heat up and squeeze in to reduce.

Adapt the machines to accept 6". Why waste all that suction...
Your maximum airflow will be determined by the smallest pipe. In this case you're killing the airflow down to around 400 cfm or so.
Penn State has the adapter for $7.95. See here. They hace lots of ductwork items and are relatively cheap.

Great I will order that today.

Have you checked the duct section at HD or Lowes? I've seen 6" x 4" reducers there.
Not experienced myself, but it seems you have a lot of dust collector for the use you are giving it. Might could have gotten by with half that. I would think that it would support a system with hoses and the proper shut off to each of your machines if you desired to go that route. I have see some professional suggest that you replace those four inch inlets on the machines with five inch or more to give better collection then a six inch hose would be more effective. I hate to cut into my new machines that way but it would probably work better.
