Sure, router tables does make a ton of dust and wood chip. 

But, isn’t it frustrating to see some dust in your router cabinet or on the floor? Even though you have dust collector installed.

I guess you do.

Luckily! I have figure out a way to improve the efficiency to nearly 100%. Courtesy diymontreal youtube channel.

The trick is that you have to:

  1. Optimize airflow in the router cabinet 

  2. And making sure you have optimal dust collection setup.

Lets see how it’s done…

Step 1 : Optimal dust collection setup

First let’s have a look at the optimal dust collection setup

Dual port dust collection system

It’s a Y-shaped dual port system:

  • That has a 4-inch hose fit into the dust collector from back of the cabinet and

  • A 21/2 inch hose connected to the 4-inch hose from back of the fence.

Don’t have a dual port system?

Here’s how to make a dual port system step by step-

Things you will need:

  1. A 4” and a 2-½” Dust port.

  2. A 4” and a 2-½” Hose.

  3. A Y-fitting.

  4. Dust collector.

  5. Hose clamps.

Attaching 4 inch dust port

Step 1: Attach the 4” dust port into the back of the router cabinet (Assuming you have a enclosed router cabinet)

Cut out a small portion of the 4” hose and connect one end to port and the other end to Y-fitting using hose clamps.

Step 2: On the back of the fence attach the 2-1/2” dust port.

Similar to 4” hose. Connect one end of 2-½” hose to 2-½” dust port and other end to the Y-fitting using hose clamps.

Step 3:  From the other end of Y-fitting connect 4” hose to dust collector.

Step 2 : Improving the airflow in router cabinet

Too often we fell into the trap thinking that if we seal it up we will get the most airflow but reality is a bit different.

Problem with airflow

It’s a really simple fix.

Since, the airflow isn’t optimal we will do few holes into the router cabinets to make sure air is passing smoothly.

The easiest way to cut a hole is using the forstner bits.

Making holes with forstner bits

You can do the holes in front of the router cabinets or at the back. It’s up to you. I prefer to do it on the back just to make sure it’s more cleaner on the front.

Holes done

Step 3 :Testing it out

Cuttign a dado seems to spill more wood dust so here’s the test is done by trying to cut a dado.

Here’s the result:

Neat & clean. Negligible amount of dust in the cabinet.

Neat and clean router cabinet

That’s it!
