Since purchasing 1.5 HP Jet dust collector, I keep switching my workshop tools and jigs to work with 4” hose.

This time, I have retrofitted my old trusted router table. Three things I wasn’t happy about – no under the table dust collection, no support for 4” hose, no sound dampening – were addressed in one shot. I have attached the tabletop to a simple 13” x 13” x 20 1/2” plywood box with a door, and that did the trick. I have added 4” inlet flange to the box, and Y-fitting to the collector to have a complete solution. The 4” hose gets connected to the 4” port on the box, and 2 1/2” hose goes to the original fence.

The hinged front door provides access to the router/bits when needed. With 700+cfm I didn’t have to make the door airtight – even with small gaps around, the air flow is great, no more mess when using routing table.

The hoses – inexpensive 4” air duct and 2 1/2” hose for Rigid shop vacs.

Nicle little build… Ive got the same table, and a possible new plan now. Thanks for sharing.

Looks nice, however, did you consider airflow to faciltate chip/dust flow and prevent overheating of router? I built an enclosed table for my router sometime back. It started as a closed box except for area around bit like yours. After some use and thought I made two changes.
1. At the port for the dust collector, a wedge shape was added to focus airflow along inside top of box.

2. On the opposite side from dust collection port, a 2” diameter hole was added to provide more air flow (cooling router)

Just something for you to think about.

Thank you for the pointers, Socrbent. I haven’t put much work into it yet, and typically I use router table for a few minutes at a time. What signs of router overheating I should be watching for?

In my case, I have a 1.25” hole on a side to accommodate for router wire, and the front door is not airtight. So the area of intake gaps is comparable with surface area of the hole around router bit – outtake.

I did not have any signs, nor do I know what to look for, but having a motor running in a box with air only coming in a top worried me.
