I looked through a lot of plans for a downdraft table but most of them were actual tables. Because of limited space I wanted something I could pull out when needed and store away when not. I found a free e-zplan on Rockler’s web site with 4 insert panels. Then I saw their new Dust Right Downdraft Table with 3 insert panels and side extensions but, it was a little too small for my needs. So, I took their plan, incorporated the side extensions, feet and a handle. The drawing called out for simple butt joints but I thought it needed to be stronger due to the constant vibration of sanding over time. So, I used finger joints for the sides of the box and a lap joint on the bottom. I then lengthened the ramps and added a bottom plate to smooth out the transition between the angles and increase air flow. I also made spacers to reduce the surface area when needed for sanding smaller parts. I can use any combination from 1 to all 4 insert panels. For the side extensions I did mortise and extended tenons for rigidity in the corners and installed inserts in the sides of the box with threaded star knobs to secure them in place. This gives me the option of taking out one or both side extensions for larger pieces. Finally, I finished it up with some wipe on poly and a coat of wax. When not in use, everything stores inside the box, under the insert panels, except the back panel, which is held on to the bottom of the box with Velcro. And so far, it has been working great!

Super cool project. I love the fact that it can be dismantled and moved easily

Update – I added a couple of c-shape holders that utilize the existing inserts to hold everything from falling out when you stand the down draft table on end for storage. The long back fence piece is held in place with Velcro on bottom since it’s too long to be stored inside the box. This has been working out great!
