Watch Matt Kenney in this router table dust seq.

Take a look at when he spins the table around to show you the back of it, there you will see dry wall screws poking out the side of the plywood. 3 of them that I can see. Now I didn't need to see this, and I don't read the magazine anylonger. I have lost respect for many of the writers over time. There are still very good woodworking writing for them, but they do so only occassionaly.
I expect more from somone trying to show you how to do something. I've not been impressed with Matt
