I am in the process of starting to build a new router table. I want to enclose the router and lift in a box so I can use dust collection for what falls through from the router. It occurred to me that if I build the box then the router will be sucking in a lot of dust into the motor because of the box. Am I just over thinking this or is this a problem I need to address in the build? I will be using a 4" pipe for dust collection located in the back and bottom of the box with a slanted board inside the box to feed the dust down to the connection. How did you keep the dust out of the motor intake? Thanks guys.
