My Dust Gorilla has been sitting around and collecting dust on the outside for long enough, so I need to get it up and running. Below was my initial plan, with the DC against the north wall. 25188 The red line is main pipe, would run along the ceiling then drop to the floor at the post, with wyes branching off of the downdrop. The blue are hoses coming off the main, 2 for the table saw and one for a router table which is yet to come. The Mini Max jointer planer outputs on the same side, there is only one hose for that.
Today I got to thinking that it would be simpler to move the DC out to the center post where the main would have dropped, which would eliminate a couple of turns and having to work around the ceiling beam (the narrow orange line).
This would would require the JP to move over a bit and assume a slightly different angle, but would still work, though doesn't feel quite as open as it used to. I'm not worried about being closer to the noise it would generate, as I wear ear protection whenever a machine is on. Hopefully you will find a picture attached at this point. You will note that I took certain liberties in how the machine was configured, as this was a mockup just to see what it would feel like to have a gorilla in the midst of things. 25187
In this location, there would be just one drop to the floor directly from the inlet. The longest hose would be under 6 feet, so static pressure should be negligable. The J/P port is about 4 4/4" (120mm), and there is no way to make it larger. An adaptor is available to work with 5" hose.
The bandsaw has a 4" port (outside dimension), Sam suggested using 4" directly over the port, then expanding to 5" to the drop. Can't see any way of making that bigger either.
The table saw has an octagonal hole in the base, over which a plastic hood fits necking down to about 3 3/4" outside dimension (what were they thinking?). This can be seen in the picture, sitting on the left side of the table saw, looking like a speaker facing up. I found a metal hood to replace that with which opens up to 5", and I'm sure a 6" is available too. I'm not much on geometry, but I think that the area of the hole in the saw is greater than that of the 5" opening, so there may be a real benefit in going to 6" hose.
This setup would make it more complicated to get a second hose for an overhead blade guard, which I had hoped to add eventually, otherwise it seems to simplify things. I would also need to build a stand, as there is no wall to mount the DC on. Oneida has a new metal stand, but they want $160 for the upgrade, and I already had supports welded to the original mounting brackets, having heard that they tended to induce a bit of lean into the system.
Sooo, before I finalize things, can anyone see any reason for not going this route over the original plan? Any suggestions?
