So I’ve been working on organizing the space I share with the garage for a while, and have finally managed to piece together something that I think works, as planned/illustrated using the Grizzly site. I plan to refine it somewhat to the exact dimensions, but its pretty close, but you get the gist. The power outlets are setup up as they are (220V for the DC, 220V for the bandsaw/jointer on the left, 220V on the back wall as well, plus high amp 110V outlets a plenty), and while there is void below the dust collector in the lower left hand corner, thats occupied by…the things one tends to find in a garage. The large box in that area reflects my wood rack/storage as it stands. The area on the right is storage currently 2 shelves for tools. The other tools indicated are a 17” bandsaw, a 14” drill press on rolling stand, an 8” G0500 jointer.

My question re dust collection is am I better to run the 6” main along the perimeter wall (as roughly indicated), or out as a main run thats ~5-6ft south off the wall with side outward drops towards the wall, thereby minimizing potential static pressure drop and maybe something I can drop down to the planer/table saw. The dust collector I’m using will be a 3HP Grizzly, hooked up to a SDD XL, venting outside. The main reason for this question is in ‘active’ mode, the planer and table saw will be mid-room (currently I’m using a portable table saw, so hence this will be more relevant in the future), and I’m wondering if I’m better getting the main duct close, or instead running a deployable flex pipe. Most of the other tools can be rolled out if I need to work with larger stock (everything will be on wheels). The grinder/sander on the workbench is temporary until I can work out the best config there, but I have a cool design for a space efficient workbench in mind that will eventually occupy that spot, and I will probably put the sharpner/sander on wheels as well, maybe as a flip top.

Appreciate any thoughts.

My thoughts: you have a very good DC, and I’m guessing that either plan will work. But I’d be inclined to do your second option, just to minimize the flex that’s would be in use. You have your tools bunched quite nicely, so none of the runs will be overly long, but minimizing the length and the amount of flex will still be a good thing.

Like you my shop has two modes. (1) Shop Mode (2) Garage Mode.
When I was designing my DC system I had to take into account the wife’s car when in Garage Mode.
I used 5” metal ducting for my system and I have a drop real close to where the table-saw is when in Shop Mode.
I use flex hose to make the connection from duct work to machine. It stores up out of the way when in garage Mode.

(Garage Mode)

(Shop Mode)

My joiner, planer, and band-saw stay pretty close to the wall where the duct-work originates so that part was easy.

Hope this is helpful.

I would go with the second option and use spiral pipe or sds pvc for the main. As Fred said above you want to minimize the flex pipe as much as you can so solid branches to get you close to the tools would be best if you can swing it. My shop is dedicated so no cars and I have an 8’ main with 6” branches off of a 5HP cyclone.
