Guess it’s not technically a table per se maybe a downdraft table top. My last table just so happened find it’s way to the burn pile, it was a total pos and needed to be permanently retired.

The dims are roughly 36”x24”x7-1/4” and made from 1/2” BB ply, 1/4” pegboard, and 1/4” hardboard (bottom). The dust collector is connected to the table via a 3” Johnny Flange. I modified the flange by cutting some of the “flange” part away so that I could keep the overall height of the table down.

The first two pictures are some dry assembly. You can see the Johnny Flange laying there on the table in the first picture. The second picture is shot that shows how the bottom is angles up so that you get suction at the end furthest from the suction hose.

The last two are action shot of the table.

I need to stop by the hardware store and pic up some varnish and give her a couple coats and this one is in the record books.

I had one like that when I had my cabinet shop but sold it when I closed the shop. Sold it for more than I had in it. But I really need to make another one as it gets too dusty in the shop without one. Thanks for the post.

The hole for the Johnny flange was cut on the drill press with a beam cutter set for a 4” diameter. I then used a hand-held router with a chamfer bit to cut a 45 degree bevel on the inside edge. The chamfer allows the Johnny Flange to sit flush on the inside. I use 1/4-20 bolts to bolt the flange to the face plate from the inside. You can mount the flange on outside of the plate but I think it gives a little cleaner appearance with its mounted through the plate from the inside.

Thanks for the comments!

I made one recently too, seem to be popular items. Yours looks lighter than mine, and probably cost less also. Nice job.

Very nice. If I ever sand anything again I will wish I had one of these.

Nice job Chunky. We all need to make one of these and many of us (including myself) keep putting it off and then we complain about too much dust in the shop. I guess we are our own worst enemies. Maybe a good 2010 New Year’s resolution? Thanks for the blog.

I put the downdraft table to good use today and it works much better than I had ever hoped it would. One thing that I’m going to change sometime is to add legs and make it it’s own free standing unit. I like the height of it when it’s setting there on the out feed table but I would prefer, and my back will thank me too, if I can get it much lower so I can sit in my chair and sand. After a bout 2 hours in the shop, I’m whipped.

Thanks for the comments!

Good idea about making it sitting height. I may eventually do that with my benchtop downdraft table.
