Wow! Be careful with that! All of those places for hang-ups in an out-feed table is a disaster waiting to happen. At least, continue the dadoes all the way clear until you can find a better place for this, or until you can redo the top in a safer way.
A safer top could be made with lots of 1/8" diameter holes, and hit them all with a countersink. Cut your miter gauge slots first next time, so you don't have any edge penetrations. I'd still be aware of the possibility of a hang up in certain situations, but as it is, you're running too much risk.
Appreciate your thoughts, what I didn't say in my description was that I've had this table for 12 yrs. In all these yrs I've never had anything hang up on one of the holes and I use the saw every day. I just don't think it's a concern in my case but thanks.
I like your idea of double duty table. It all makes sense, however, how would you tie it in to you dust collection? And I see that there is a vent on the bottom side...would than not detract from suction on the top?
There is not much discussion of the air handling part of this. It looks like the filters are in tandem for extra elimination of dust.
Does this thing perform well for other than settling dust after sweeping? Do you sand on it?
Air changes per hour is a good indicator for someone considering something like this. I think this is a nice idea and also think the air flow capacity wants to be robust for many woodworking operations.
I hook a hose to my sanders, do most of my router work on a router table (with dust pick-up) and vacuum my floor with the same hose. Fans exhaust the air.
