First, my Freud came with dust collection. However, it's ONLY about a 2-1/2" line and throttling a 3hp, four bag collector to that doesn't sound like a good shop practice.
Second, even with that kind of collection backing the table, the shelf under the router always caught a lot of dust and chips. After all, chips deflect, when they hit something, and can go everywhere, except into the trashcan across the shop.
The solution was to box the router in, which poses a risk of interrupting the cooling processes. The air for the motor has to come from somewhere, so it'd pull from the area of the router bit. As such, I ran a second line to the box.
In the end, after several long runs, I end up with, maybe, a tablespoon of sawdust on the table top.
I suppose, if the "ain't now sawdust under the router" thing were true, the ideal would be a four inch hose on top and a two inch at the box, along with a small intake, so the lower hose was less likely to pull from the area of the bit.
SIDE NOTE: I have a sanding table, on which I installed sides, a back and a top. Before doing that, it was barely worth using. After, it's one of my most treasured tools in the shop. Since the upper sides, back and top are nylon, I can stick long things out the sides or back, if need be. Otherwise, it'll handle things a couple feet wide.
When I sand, you can see sawdust flowing off an item and being drawn into the table. Even sanding exotic woods that you can, easily, smell, don't. As such, I also use for carving and grinding too. When it's clear of acting as a horizontal storage area, it's my go to place for free-hand routing. ALL the fines are captured and, depending on how I handle a piece (control the direction the router is tossing stuff), only a small percent of what the bit kicks off makes it to the shop floor. Still, there is enough that I vacuum (4" hose and tube) when I'm done.
Clearly, even good collection can't stop every bazillion mile an hour chip from escaping.
The reason I have what you want is, I never lent it out before.
Scraps are a myth.
