This is an update on the Downdraft Table/Box I made awhile back.
I really like it, it is the same exact design as the previous one I built years ago, but instead of 1/2' holes it has 3/4" holes.
The dust collection is way better than the old one and does a far superior job, I do use a waffle mat to cover about 1/3 of the area under the work piece. This quiets down the sound of the piece I am working on vibrating against the top. The side boards really improve the dust collection too.
