Dust Collection Question
Hi folks. I'm a hobbiest and newcomer to the forum. This is my first post.
I recently finished building my first router table - a melamine variation on the NYW design - and I'm surprised by what I've encountered in my dust collection set up. I spent a lot of time trying to figure out how to best configure the cabinet cavity underneath the router to channel dust into the 4" dust collection port at the back of the case. (My dust collector is a ClearVue cyclone.) I didn't pay as much attention to dust collection at the table level - I just hooked up another 4" hose to a plastic blast gate attached to the fence.
What surprises me is that I really don't seem to get much dust in the cabinet cavity because the fence hose seems to grab almost everything. (I've only used the table for edge routing so far.) Somehow I figured that I needed a big space surrounding the router because of the volume of chips and dust that would be flowing down there. If I had known that dust collection down there didn't require a big space, I probably would have made a much smaller cavity and used the savings for another drawer or something.
Am I missing something? Is a lot of space needed around the router to generate air flow to keep the router cool? Or is there some other reason for not making the cavity as tight as possible without restricting access to the router? Or is that, in fact, what people who know what they're doing do, and I just screwed up?
