Simple down draft table for sanding. I probably went a little overboard on the construction since I used locking rabbet joints at all the corners. I was going to use pocket holes but then decided it would be better to practice some joints than do it the easier way. I used some scrap plywood to channel the dust to the middle and plan to further seal the cracks with some silicone sealant. During dry assembly I realized the longer side boards had a bit of a bow to them so I came back with some steel rope and a turnbuckle to pull it all together. Not fine woodworking but it got the job done and once the peg board is on top it can’t be seen. All said and done any dust that stays out of my lungs is well worth the effort.

I haven’t had a lot of time to test it yet, but so far any dust the sander makes is quickly pushed down into the holes and sucked away.

If I were to change anything it would be making sure the plywood isn’t bowed. I plan to seal all the cracks below the pegboard with a bead of silicone as soon as I get time.

The horizontal supports under the pegboard are a must and do a pretty good job of supporting the weight I’ve put on it so far.

Nice project. Did you use a shop vac or a dust collection unit. Just wonder how much would be too much suction.

If you’re planning to seal the joints with silicone, how about using construction adhesive instead so it will lock the bowed plywood at the same time. By the way, using a Deputy is the answer here – good idea !

Best,

Serge

Nice idea and good fabrication, I have a torsion box for assembly, and your design inspires me to add that to the lower side, and get 2 functions for 1 tool space.
Space is always a problem no matter how large or small your shop is. They seem to shrink with age.

Thanks for you inspiration

Did you come up with this design? My dad has the exact same thing in his shop. I’ll have to ask him where he got his design from.

Not my design, it was based off of many different designs I saw online
