The Rockler jig is wide open on the bottom side and top. Look close at both and you will see the difference. Whether from the top or not with no closed off sides this rocker jig is about 80% less effective than the type jig where there are two sides coming down around the sides of the wood. With the Rockler jig the suction is not focused on any area, it is wide open. There is no cavity formed for the suction to work on at all on the Rockler jig. I have the Rockler jig sitting right here and it spurts dust all over the place in use.

I don't know about the dust collection but it doesn't look like that jig gives much help with vertical alignment. Seems like the router has to balance on the 3/4" edge of a board.
I had an idea how the Festool jig could be made to self center. If the base plate had one pivot point and one slot for each guide strip ,and the pivot points were on opposite ends of the guides you would get basically the same jig as the Rockler but the guide strips would help with vertical alignment.
What do you think? I'll have to try making one so I can show it more clearly. Any Sketch-Up wizards want to try drawing this?

nickao said:Micheal look at the Rockler plate. There is nothing to cap the top, ie no space for the vacuum to pull. You have to replace your existing plate to use it.
It's like when I use my DeWalt router, if I forget to put the top cap on, the dust collection is crap. With the cap it works great? Make sense?
It's not worth the discussion, well I guess it is worth the discussion, but I have used it and the collection is dismal. Just try it and you will see what happens. In the real world the jig with the sides just work better in my experience for alignment and dust collection.
I guess you can add this Rocker Jig to the bottom of an existing plate that has a top cap. That should work better..
