I am installing dust control in my workshop with the ductwork in the attic above the shop. I do some woodwork, some metalwork and some automotive. In the area of the shop where I would work on a car, I have clustered together a table saw, planer, jointer, band saw and a belt/disc sander all on mobile bases so they can be moved out of the way when a car is in the shop. I plan on installing one 6 inch drop to serve all of these machines. I have 10 foot ceilings and would like to come out of the ceiling with a 5 ft. 6 inch metal drop with flexible hose attached to the metal pipe so I can attach it to each of the several machines.
Now to my problem and my question - The drop will be in the way of a car pulled into the shop. I need to mount the drop on a hinged joint or swivel of some sort so I can lift the drop up to the ceiling to get it out of my way. I could just run the entire drop with flexible hose and pull it up to the ceiling via rope and pulley when not needed but I would like to do it with as little flexible hose as possible.
I have been lurking here for quite some time and have seen some ingenious ideas carried out by the intelligent folks here at Sawmill Creek. Although I have come up with some complicated ideas of accomplishing a hinged swivel joint in 6 in. pipe, I need a simple way of doing this. Any one here have a drop like I am looking for? If so, could you post a pic or a drawing of how you accomplished it?
Thanks, guys!
