ive made a pretty nice fence set up for my router table and for the most part it does a really good job however ive discovered something it cant handle and i wonder how you guys deal with this

the problem im having is when making a dado in a piece where the opening in the fence is blocked by the piece that you are routering. the saw dust just seems to shoot out the dado as its being cut and flies across the shop. not much chance of really catching it. is this something i just have to live with?

I know exactly what you’re talking about. If someone has a solution, I’d love to hear it.

I don’t know if it works or not and I’ve never tried.

someone on another site mentioned under table collection as a possible solution. ive never tried it as i get very little dust inside the cabinet. i always thought having 2 sources of collection fighting each other wouldnt work as well

I have dust collecting built into my cabinet and fence and it doesn’t help. I stick a 5 gallon bucket on the floor at the out feed side of the table. It catches a lot of the detritus.

I have one of the Big Gulp type dust collection “horns.” I’ve got ideas of attaching it to the out feed side of the cabinet, big gulp pointing up, to help direct even more dust into the bucket. But I haven’t done it yet.

Steve Maskery did a video showing his idea – he just drilled a hole(s) through the table in line with the bit so the dust gets pulled down into the cabinet. I can’t see the video from here, but I’m sure this is it.

I’ve done similar things to what Mike has shown. Set up dust collection to catch the stream of chips. I have always wondered how under the table dust collection would work, maybe with the largest opening (insert ring) in your router table? I have my router in the wing of my table saw and did have under table dust collection for a little while but it was a pain the way I had it set up.

Funny you mention this, i had a buddy of mine come over yesterday to build some fishing rod holders and as i was about to start routing the first dado he stands right at the end of the board waiting to catch it. Wouldnt ya know it, i covered him in saw dust from his belly button to his knees.

Thats my answer to the question … have a buddy catch your boards and he will take most of the dust and chips with him.

Hey Mike, Once you get your DC figured out you can stop by the house and fix mine up too. I am really like the way your router table has turned out even if it does make a mess while routing dados.

This looks interesting and specifically mentions a dado cut…

I use the router fence that came with my Grizzly router extension and it catches +80% of everything. All the chips are sucked up and only the lighter dust makes it out the front of the fence. Of course it helps that the Triton router has a built-in dust shield and 1 1/4” hose hook-up (for under the table DC) and works well with the fence DC above.

My router is built into my tablesaw extension and has a combination of fence & under-table collection that’s very efficient. When cutting a dado it captures 100% of the dust, I never see a speck. The trick is to remove the plate ring or to use one that way larger than the bit, if the ring is too tight on the bit it can throw dust forward in the already cut-dado. And to have a big-enough DC to generate enough airflow.

You can see the partially finished setup at, I need to update now that it’s almost finished but you can get the idea.

Yeah, I should probably use the larger holed insert and that would minimize what dust/chip blowback I am getting. FWIW, I use the smaller holed insert in order to set the bit height and forget to change the insert later. I just love gettin’ old AND lazy both at the same time… LOL

Greetings Mike,

Here’s my suggestion: Just get a cardboard box and set it on the floor at the end of the outfeed table.

As you cut the dado and push the workpiece along, the chips will “shoot out” the end and fall in the box…simple. When you’re done, empty the box…

At this point, I have rotated the router fence 90degrees counter-clockwise and route standing in front of the saw. BTW, if I don’t make ANY mess at all, the lady of the house starts thinking I haven’t been doing anything out in the shop… ;-)
