outfeed/downdraft sanding table

I needed a new outfeed table for my table saw and decided to to build a combination outfeed table and downdraft sanding table. I searched all over the net and found examples of other peoples tables and incorporated all their ideas into my own. This thing works amazing. One of the things I like best is in the winter when the shop is closed up and I sweep the floor I turn it on and the usual cloud of dust that forms from the sweeping dissappears in minutes.
It is built from birch ply and the top is made from MDF. I sprayed the top with a couple of coats of prekat laquer and then waxed it. The hardest part of the entire build was drilling all the 1” hole in the top. I think it took me over 2 hours to drill them all.
the fan motor was given to me by a freind and is one of those squirrel cage fans from an old heating system.
I installed a timer switch from lowes and an outlet to plug my sanders into. The timer keeps the motor running for up to 1 hour. It’s great if I sweep up, or sand then leave the fan running while I go to lunch. when I come back the shop air is cleaned.
I istalled 2 stiffeners (see photo 4) on the underside of the top to keep the top straight. total cost was under $150 and the most expensive item was the leveling feet.
If I was making it again the only thing I would change would be to add a kick space for my feet when I sand.

I use 4 heating filters I bought from a home center to catch the dust. The filters work well but you do have to clean them qute often. I will probably attach this sanding table to my dust collection system in the future.
I couldn’t be happier with this low cost dust solution.

Looks good! Have had one of these on my list for years too. My uncle (in the HVAC business) got me an old 7 speed blower they use to have at their church before they upgraded.

I have a mini box I can set up on my TS or bench for sanding that hooks up to my DC. Wonder which is more efficient….....big setup like this or connecting it to your DC?

That is a great idea and use of space for a downdraft and outfeed table combined. It gave me some ideas about using some of my open space under my outfeed table. One thought that came to mind was hooking it up to a dust collection system would also allow it to be used for routing also. I rout alot on top of my outfeed table and a downdraft setup going straight to the dust collector could certainly help.
I have a 36”x96” outfeed table but using possibly a 23×36 section on the end would allow greater suction at each drilled hole.

Hey Greg,

Stealing my thoughts? Again..LOL

I was going to suggest washable pre filters? I use them in my shop to keep larger dust particals out.

Possibly a rectangular funnel shout feeding into dust collection? with a door for router access?

By the time I’m ready this multiple table will be figured out. LOL!

Nice shop project!

I wonder if you would be money ahead if you used cleanable HVAC fliters? I like it and the idea of using an old motor instead of it ending up in a scrap yard.

-- But I did measure it twice and cut it three time and it still is to short!

This is great, and I’m totally sold on the concept… my shop is too small/weird to support an overhead unit, so something like this would make a good second-place. I’m especially desiring one after I spent an hour sanding yesterday and got a coating of dust on every single thing in the shop. I’m hoping to build with walnut so I should probably sort this out ASAP.

So just out of curiosity – did you integrate your tablesaw motor into this somehow? or is your tablesaw not belt driven? do you have any drawings for the project? I would like to see the interior dimensions as I definite won’t be able to make mine as large. Does anyone know if a rectangular form will work just as well, or does that proportion cause problems for the airflow?

I’m guessing that the more space for your table the more cfm per minute will be required? I’m thinking about this with a hood of some sort to funnel the air and dust? Friend built an open ended dust, chip vacuum for his lathe, and it seemed to have difficulty, although it was not a down flow set up. Just some thoughts.
