I had a chance to use the base mounted chip catcher on my Festool OF2000 router last weekend. I was working on a countertop that goes up against a wall that is nowhere near straight. After using the old countertop for a template & cutting the profile with the jigsaw, I attached the lower support board and got ready to match up the profile.
The countertop is 10' long & in some places I had to remove around 3/8 inch if stock. I used a 1/2 dia bottom bearing flush trim bit with straight flutes.
With the chip catcher installed on the router, the dust collection was excellent. Lookin at the floor when I was done you couldn't see any additional sawdust. I'm going to estimate 99% collection on this operation. Very impressive.
