You should also cut out the piece of metal on the face of the inlet that would normally stop any chunks of wood from going through the impeller. This really impeads on the air flow and with the metal impeller you don’t need to worry about hurting it.

These types of dust collectors need sufficient air flow and don’t really produce a lot of vacuum, so you need atleast 4”. Get rid of the cheap wye it came with and pipe everything with 4” SWV pvc. It is cheap and lightweight. My planer has like a 3” hookup so I am using a fernco fitting(rubber coupoling with 2 hose clamps). You can find them at hardware store in plumbing section.

I wish I could get better dust control for my router table. It will be a project to master before the summer is over.

good luck
