The need to control sanding dust has been evident in my shop for some time. Like most small shops, work space is at a premium and a downdraft sanding table has a substantial foot print. I looked at several of the tables available and decided the table top models were too small for the type of woodworking that I do. The next obstacle would be where to store it when not in use. With these requirements in mind I went looking for a sanding table to fit my needs.

About a year ago I joined a woodworking forum called WoodNet. My first post was on “Why clean your shop” and one of the members (Michael Curtis of South Carolina ) posted several pictures of his downdraft sanding table. Those pictures were the inspiration for my shop built table. Thanks Michael. The pictures of his table are on page four.

My new table is a self contained sanding table and workbench. It solves the issue of where to keep the sanding table when not in use. A solid workbench that measures 28″ x 88″ x 34 1/4″ high. The frame is made of 2″ x 8″ pine and is supported by 3 1/2″ X 4″ laminated maple legs. The top is two pieces of 3/4″ fir plywood laminated and banded with hard maple. At a later date, I will be adding that one thing that every workbench needs… a vise.

I used this Jet dust collector model dc-650. After removing the two bags and hose, I unbolted the base and cut 6″ off the tube that is attached to the motor. Using the flange that held the top bag, I screwed the dust collector to the bottom of the sanding table. A thick bead of caulk was applied around the flange and to the intake tube, where it penetrated the bottom of the table.

After installing the lower bag and connecting power, it was obvious the bag was too small and restricting the air flow.

I ordered a custom bag from American Fabric Filter co.

The $140.00 bag fits like a glove and with nearly three times the volume as the original bag, it really does the job. A huge zipper across the bottom will make this bag a breeze to empty.

This is a great idea. Hadn’t thought of modifying a dust collector. Thanks for posting.

Nice, love the idea, thank for showing us cheap minded woodworkers.

I will see what I can do to get you one…or I could send you a sketch and you could build one for yourself.

It does work very well but it doesn’t make sanding any more fun.

You are welcome. Thanks for commenting.

Hello Div,
Oh No!! What have I started?
Maybe I’ll put some sketches together and anyone that wants to build one can. It would be fun to see the different variations.

Keith, this is a pretty good idea and, a bench like this, is something that most of us with shops that need multi-functional furniture could use. I have been considering building a down draft table but could not justify giving up the space. This certainly looks like it would be an interesting build.

Hello Scott,
For me, it was one of those projects that was needed. When it was finished I thought….why didn’t I do this sooner.
Thank you for commenting.

Hi Keith, I too will thank you for posting as it is a great idea and I could certainly use one in my basement shop. It has been favorited.

Thanks again.

Thanks Chris,
I have a friend who’s shop is in his basement. He goes to great lengths to control dust.

Excellent concept, beautifully executed. I am going to go out on a limb and make a prognostication. I predict that, in less than a year, that top will be in at least two pieces so that one can remain flat, with tools and stuff on it, while the other is lifted up to access the sanding table.

Again, my compliments on victorious venturi work!

Hello Lee,
A friend stop by the shop last week and made the same suggestion. It is by no means out of the question but I will tell you this, if I make any changes to this workbench, you will see them here first.
Thank you
