Topic tags/keywords: router table dust collection shop made

So I’ve had this bench top shop made router table for a couple months now, and I really do like it.

The problem I’ve run into is that now I am getting more diligent about dust collection, using the dust deputy (which I love). The dust port on the back of the fence works well only if I am doing a through cut and don’t totally cover the hole in the fence. When I cover the hole, the suction from the shop vac creates a big drag on my workpiece! And also barely collects the dust, which mostly falls out the bottom.

I have already picked up a nice piece of phenolic faced 3/4 ply, some t track, and a mitre track, with the intention of redoing the top to reduce friction and get a better fit. Any suggestions about changes to the fence or the table body to improve dust collection here? All help is welco,e!

When you completely cover the opening in the fence you lose airflow to the vac. You need airflow for the vac to function. You might try modifying the fence (a split fence in the front with a larger opening on the back fence for the airflow). You might also modify the dust collection attatchment on the back with a wye pipe or a hole drilled into the top to increase the air and reduce the suction on your work piece.

Here is a very cool router table...

He made a Lift… and a Super dust control design…

Get some ideas… Maybe you can use some of them…(??)

I would try to space the dust port like 1/2” from the back of the fence.

I would close up the back of your table with some 1/4” ply and add a second dust port near the bottom of the back piece. Any debris the DC misses will be pretty much contained to the space under the table and easy to vacuum out.
