I’m building a stand alone router table. I have purchased the Bench Dog Cast Iron top and the Incra router lift I plan to build the stand with Baltic Birch Plywood and use a modified Rockler router table fence.
I’m running a central DC ((Laguna C Flux) with a 4” suction line to a shop built Dust Bucket with a branch to the fence.
I have two questions:
(1). I have seen two configurations of router table DC set ups. One configuration has a 4” line going to the dust bucket and a smaller (2 1/2’??) Line going to the fence. The other configuration I have seen has 4” lines going to both the bucket and the fence. My non technical intuition says that the latter (two 4”lines) will provide better dust collection. But most of the configurations I see have the 4” dust bucket and smaller fence set up. Can any engineer members explain which configuration is best?
(2) In researching the set up of my shop wide DC system, most recommendations were to avoid right angle turns in the piping because they reduce DC effectiveness. Yet Rockler sells a T connector for splitting the dust bucket, fence lines. Wouldn’t a Y connector be a better choice?
Thank you in advance for your responses

I’d go 4” to both.
About a year ago, I bought an Incra router table top and made the fence and router enclosure.
I have 6” HVAC snap lock main lines coming from my 2 hp Grizzly, then a wye to 2 4” with flex hoses, so one to the fence and one to the router box.
I’m amazed how well it pulls chips off the bit.
Since you have the option, go big if you have the dust collector to support it.

I have mine setup the same but using the Y-connector off of a main 4” hose. Works good.

...use a modified Rockler router table fence…

I think that is your weak link. Take a look at the Incra WonderFence that does an excellent job with dust collection. I have this setup along with the Rockler ‘T’ that you mentioned and it works great

“This coupling fits both 2-1/2” dust collector and 2-1/4” shop vac fittings”

So all of my router table dust collection is home made. I have used a single 4” hose that I split to go to both the fence, and the box. worked well, and kept everything clean.
When I made my latest router extension table I skipped making a new bucket. And only use the fence. Same 4” hose that is adapted down to 2 1/2”. My fence is the same style as the Incra wonder fence. It works almost as well with out the bucket. Very little dust makes it below the table. I do have a woodpecker router lift, with the extra rings. I keep the smallest ring possible on the router. I feel this helps.
