With my craftman table, at least half of the debris winds up below the table with the shop vac connected to the fence, and of course there is nothing to catch the chips when I am not using the fence.
Accordingly, I am thinking of closing in the bottom of the table, and putting the port below the table, rather than above. Since the largest hole in the table will be where the router bit is, it should catch all of the debris.
Does this make sense to do? Will the DC be okay with the restricted opening for air flow?
