I would like to build my own dust collection system for the underside of my router table. Any suggestions drawings pictures of ones that you have built. Also is it better to have the dust port directly underneath the router or to the back like on Norm Abrams table. Also should I stay with 4” or go smaller. I want to capture as much dust as possible.

I have a shop vac mounted to a hollow fence. When routing edges, against the fence, it gets 99% of the dust. But, if routing dadoes, it gets 0%. Ideally, Having dust collection in both the fence, and having a sealed cabinet with dust collection below, would be best. But if all your routing is doing edge work, then the fence alone is probably sufficient.

I split my 4” into 2 – 2 1/2” using a 45ยบ “Y”. One picks up on top of the table through the fence, the other under the router. I cut plywood at compund angles and put them in place under the router and sealed everything with caulk. The cavity is just large enough so the router and lift can operate freely. I estimate that I get 99% of the dust & shavings when the fence is utilized and somewhere around 80% when I take the fence off. It is remarkable how well it works. It took a year or so of trial and error to get it to work this good.

Greetings Mike: It’s all 6 of 1, and 1/2 dozen of the other. Everybody does it a little differnt , but yet the same. Over, under, behind the table. Just everhow you want it. Both ways…... pick a size…. 2”—4”. None. When you think on it, they’re all the same set-up. Whatever works for you, I’m all for it. Keep on keeping on.

I have a Kreg PRS2000 table.

I “enclosed” the base by cutting 1/8” hardboard and leaning it against the legs. The suction pulls it in, so there’s no need to affix it … for now.

On the back, I installed a 4” DC port and a 2-into-1 adapter, used some 2 1/2” hose to get from the adapter to the upper router table DC port, and hook my DC into the 4” port on the adapter.

All in all, it works quite well. After a LOT of board feet, I have to vacuum out the base on which the table sits, but … it’s simple and contains the dust just about perfectly.

I built Norm cabinet. When I used with the fence I get a large amount ~85% of the debris flying out. If the bit is buried in the fence and I am taking small amount off it is even better. Most of my mess is when I don’t use the fence (say a round over bit). For that situation I took two pieces of ply about 10” and 6” long by 3” inches tall and tacked a 6”x10” piece of hardboard onto it and put a 2 1/2” port in the top in the corner. It helps allot but still doesn’t catch everything.
