Shop-Made Mobile Outfeed/Downdraft/Assembly Table (2003)
Here’s a picture of the internals of the
downdraft table. On the left you can see the opening for the
4”x10”x6” register boot. I added a piece of 1”
aluminum flat bar down the middle to add support for the table top. The
bar had kept it from sagging even when I place my OSS on top of the
downdraft table. Also notice the “baffle” that extends from
the far end of the table to a few inches from the inlet. This has
dramatically improved suction to the end of the table furthest from the
inlet, and I now have much more uniform suction across the entire table
And here’s a detail closer shot of the
top of the downdraft table. I hook a hose up to the register boot when
its in use. It works GREAT!
Credits: The design of the downdraft section was inspired by Terry Hatfield. He has a good description of his benchtop downdraft table on his web site. I changed the design by building it into my outfeed table and adding an internal baffle to improve airflow to the holes furthest from the inlet (see pics above).
Minor upgrades: After using the table for a while I decided to add a roll of builder's paper to the side of the table. I use the table to assemble and sometimes finish projects, and I find that the roll of paper makes it very easy to protect the surface of the laminate from damage. Since builder's paper is super cheap at any Big Box store, I use it often, and it's nice to have readily available. Here's a pic of the table with the paper roll:
