Double checking main line layout
Could you fine folk please cast an eye over this basic layout of my main ducting line and comment or confirm that I'm on the right track?
It's all 6" PVC pipe which will then, at the closest possible points, lead off into the required sizes of solid and/or flex for each tool: table saw only on far left - right hand side will be changing between jointer/bandsaw/drill press/thicknesser/router table (small shed space, machines on wheels moved into place when used)
The right side line has a screw cap on the wye to close it off until I get that side installed and so I can block it off if/when needed.
The open end on the left is something I'm not sure of, but vaguely recall reading somewhere here that I needed it. If not, I'll probably just throw either a 15 deg turn in or make it go straight down at 90.

You only need it if the take offs are smaller than 6" otherwise I would close it.

I put a vote in for the left hand wye but capped, mainly for maintenance reasons, if you do have something go wrong in the main line (blockage/fire) you can get in there relatively easily and it allows you to extend at a later date, otherwise a long radius 6" bend/45/15°?? instead of the wye,
also as a suggestion put any blast gates in your drop down legs as close to the main line as possible, if you have the BGs down low the downstream legs will fill with dust

Thanks fellas.
There's no room for extending the main line so I've gone for a longish 2x 45 bend on the left and started making up a blast gate for the right. I'm hoping to make the vertical section (and corner) on the left easily removable in case I need to get into the ducting.
It'll be nice to have it finally working seeing as I finished building the cyclone 6 months ago
