Default Under the table dust collection

I'm interested in getting my first router table. I'd like to have some under-the-table dust collection for operations like dadoes and grooves and joinery like making box joints and dovetails with a jig where the fence-mounted dust port is of little use.

I've seen four options thus far:
1) Incra CleanSweep downdraft box. Looks great in their video. However: you are supposed to use it with their rings which have been slotted to improve airflow. Which is a clever idea. But that means buying their plate or lift, whereas I think I could get more for my money elsewhere.

2) Rockler has a similar product, called the Dust Bucket, with no mention of the need for slotted rings. So I'm left wondering whether that feature is necessary or not. Is Incra over-engineering it? Or has Rockler not actually thought it all the way through.

3) A router with a dust collection port built in. My choice would probably be the Triton MOF001. But does this feature actually work?

4) A dust collection bag, which I guess would have to be adapted to fit a router table.

Any thoughts?

This is a dust collection option from Lee Valley meant for their steel table top. Veritas® Magnetic Dust Chute - Lee Valley Tools
This is one from Grizzly. There's a 2 1/2" hose sticking out the back of the fence in the 3rd picture. Grizzly.com
Woodpecker's setup. You can see the hose connection behind the fence. Grizzly.com
Grizzly's starter router table and fence. If you look through the pics you'll see where the dust pickup is. Grizzly.com

I'm sure there are other examples of the same thing but the point is they all put it in the fence because it works well there. Its true that none of them will work for dadoes and grooves. If you plan on doing dadoes and grooves you should keep in mind that the size of piece you'll be able to do this on will be limited by the size of your table. In other words, you won't be able to do a very large piece like bookcase sides. There are 2 very good dado and grooving jigs that have been posted on the forum for doing them handheld, one uses guide bushings and the other doesn't. In those cases, hooking up some DC to the router is nice.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

If you're a sucker for paying high prices for something you could make, .......
Build a box under the table and connect a hose to it.

Never, under any circumstances, combine a sleeping pill and a laxative on the same night.

Axl, yes, I can build a box...still outstanding, however, is the question of whether the rings that Incra offers, with the slots for increasing air flow, are necessary for the box to actually work.

Harvey, it should work with out the Incra inserts, but the only place for dust to go is thru the hole arond the bit. The smaller that is, the more the extra holes will help.

Some will tell you that under table DC is not needed, but if you are cutting dadoes, fence based DC is useless. For edge routing, good fence based will get most of the dust.

Many routers have dust collection adapters that work quite well, also. Still for edge routing in a table. fence DC probably is better. The inserts with holes would improve DC that way as well.

Over engineering? No. Do you need it? Depends on your use, and how effective DC you want!

Hope this helps make it clearer than mud!

I have found that hand tools are the best choice when I want to make mistakes at a slower rate of speed.

I don't suffer from insanity. I enjoy every minute of it.

I was running just the 2-1/2" hose off my fence, then built a box with an access door for the underside. With my 1-1/2" connected to the top, the system did a fair job of pulling chips and dust. After I installed the box, I have almost no dust at all. The box even seems to help pull sawdust away from the router.

Obviously, if you are going to install a box, bit changes become a consideration. I have a lift, so that's not an issue.

The reason I have what you want is, I never lent it out before.

Scraps are a myth.

Dejure, are you using a shop vac or a dust collector?

Harvey I built a box under my RT that uses a 4" hose from the dust collector and have a 1 1/2" hose from the shop vac for the fence. It looks to work as well as the Incra system and Rocklers box. I use the smallest ring possible on the plate dictated by the bit being used. I would imagine Incra's various slotted inserts would help some but would not be a big difference to my set up using the phenolic plate from MLCS MLCS Router Accessories 1

I do not have a router lift. My table has hinges on the back side and is lifted in the front and braced up by hinged legs when changing bits.

I couldn't see what equipment and tools you have so unless you currently have a dust collector you would have to way that investment against using a broom and dust pan for a little while

I have 2 tables with the Incra Magna Lock plates, one with a Triton TRA001 and another with a Milwaukee 3.5 HP router.
I have used the non slotted rings for a long time and recently purchased the slotted ring set.
The difference is amazing, especially when routing dados. The sawdust is captured as the stock leaves the bit, no dust rooster-tailing off the table.
I use the Peachtree Dust Bucket instead of the Incra because I already had it,
