Router Table - Best Dust Practice?
I have a big glaring elephant in my workspace, in the form of a Triton router set into a Kreg insert mounted on an extension of my tablesaw wing.
I don't use it all (yet) because I am undecided on how to deal with the dust from it.
My last router table (given away ten years ago) had a GMC router attached to it, quite heavily modified (ie without a base plate - mounted direct to the table) and I had a 4" hole drilled in the table immediately adjacent to the fence with a fence inspired by this one from FineWoodWorking in 2001.

I didn't have any baffles below, nor a vacuum cleaner - I just had a 4" dust extractor fitting in the back of the cabinet, and to be fair it all worked reasonably well. (which leads me to believe that I'm over thinking this).
I can't do exactly that in my new setup, because I am not going to take an angle grinder to the Triton Router.
What I can do is modify the Kreg inserts to get the equivalent area to about a 50mm dia hole - I have also access to a 100 diameter fitting below the bench and an 80mm above (both shared with the TS), of course I have the option of using the vac as well.
My thoughts are to use the 80mm in the fence (it's not possible to make that bigger) and despite the indisputable fact that the 100mm will be completely choked, plug it in anyway. If I extracted from below I could simply build an 80mm bellmouthed hood over the fence - but I suspect that would be pretty cumbersome to work around.
Because none of that makes sense to me I'd like to see if there is an alternative before I spend anything on fittings and so forth - I have a mockup fence with an 80mm connection in it - works OK, but will the downdraft work against it?
Note for lots of reasons I am stuck with the size of connections I have - but can they be made to work to either suppliment or be supplimented by the vac?
Can anyone save me from overthinking this?
Cheers,
P

Your definitely over thinking this.
As far as router tables and dust goes, this thread is as far as i'm concerned the bible for effective dust collection on a router table
Automated Router table
No fence or overhead as the lesson was that doing that you fought the nature air movement and better collection happened as shown in the thread

My router is on a TS router wind and the router fence is attached to the TS fence. I put a bit of effort into incorporating dust extraction into the router fence when I made it 15 years ago.
A few years ago I upgraded it from a 75mm to to a 100 mm with an inverse BMH.
The flexy it uses is the same one as used by the floor sweep attached to the TS OH guard.

For underside collection I needed something quickly and so set up a a plastic crate occy strapped to the underside like this.

Start and stop is no problem as I added a remote no volt switch before the plus.
However, it's a bit of a PITA to use for router adjustments compared to a cupboard but it is highly effective for dust control.
The flexy it uses it connected via its own blast gate to the underside of the TS.
WIGRTI I might build a cupboard.

My router table uses above and below collection. The above is via the fence, and the below is at the router bit via an in-built dust sprout ...
... using the Festool Router Table twin hose system, and into a Festool CT 26E.
The dust collection is extremely effective. Barely any dust escapes.

@BobL I actually laughed! When I said "cupboard" in the post above I really meant "plastic crate" - at least I had the good grace to use some hanger bolts and wing nuts to hold it in place! Bungie straps are next level!
I was actually thinking of using a 20l bucket this time, but I like the clear.
In your setup, where does the "air in" come from? I used to have about 25mm of gap around the top to ensure plenty of cooling for the router, you don't seem to have any?
I am pretty sure that I'll run with this - in my case 80mm (3") to the top allows plenty of suck if the 100 below is throttled back a bit.
I love your wingnuts to TS fence connection too - I've been using clamps, but may well take your wing nuts and modify a couple of Derek's micro adjusters -
Here's my current fence mockup- without the aluminium extrusion or HDP bits - get the dust sorted and the rest will follow!

Thanks Phil - I guess overthinking is just part of the hobby for me! :
The link has the risk of me going down an entirely different rabbit hole, but for now I don't have space between router, insert and TableSaw to go ahead - it's actually the same concept as the original drawing above I think - apart from the "bullet proof polycarbonate"! At least you've given me something to think about in Mark 3.
Clearly my current preoccupation is nothing to do with woodwork or building - it's just revisiting all my gear!
Cheers,

I got this to use on my setup.
Works well. Upgraded to have a small cyclone between it and the vac.
Easy to install and works.

The router table wing has quite deep ribs which prevent the crate from reaching/sealing off the crate from the underside of the wind. Enough air gets through to scavenge fine dust because my particle counter doesn't register anything significant with this setup.
I was going to go with clamps/bolts and wing nuts but while I organised them I decide to use an occy strap and it worked so well I didn't bother with the original idea for fixings.
I use Occy straps quite a bit to suspend or force flex to hang in specific direction/ways. I'll take some photos sometime of these.
