Supporting the Dust Collection Hose for a CNC Router 
Question
Forum Responses
From contributor E: I have about 20 ft ceilings and run the hose towards the middle on the table. No swivel joint. Enough hose to leave a little slack and we use a bungee cord to keep the slack up out of the way. 5 years and it still works. From contributor B: I use a piece of 1/2" conduit held off the ceiling by about 1" with a couple blocks. A 3/4" PVC coupling slides back and forth along the conduit. My 4" dust hose is connected to the coupling. A bit of experimentation for connection points is all it takes to get a trouble-free setup. Bungee cords complete the system.

From contributor P: This setup works really well. It has been used for the last 8 months with no kinking ducts. We have a 10 x 5 table.

From contributor P: It is a Shopbot PRS Alpha with two spindles. From contributor J: Working on fabricating this one for the new shop.

I purchased a track system from McMaster Carr which is something that would be used on a sailboat, so it is strong and moves freely. The track is anodized aluminum, and the roller trolley uses ball bearings - very smooth. I used the 550 lb cap. I have a bungee cord which goes around the hose, and it stays out of the way of the machine. I tried other track systems and they were not as smooth as this one - it is not cheap, but it is well made. Do a search for page 2848 on McMaster.com. Item is 9484T41.
From contributor P: One thing to consider is the more flexible pipe you have, the more it reduces the efficiency of the extractor by slowing the air velocity.
