I put together this downdraft benchtop sanding table from some scraps I had laying around the shop from other projects. I started with a small pieces of ½” MDF, ½” ply, 1/8” pegboard and a leftover 45 degree PVC elbow. The size was somewhat determined by the scrap pieces, but the long MDF piece was 37” and 13” wide so I landed on a 14” x 23” box 6” high.

After cutting a 4” hole in the end piece I put the box together with glue and brad nails, nothing fancy here. Then I ripped down the ½” ply to the right width of the box and figured out what angle I needed to cut the ends at to get the proper slope. 12 degrees turned out perfect and I put some side supports under the dust chute.

Instead of rabbetting the top in I used cleats from the dust chute cutoff. I used a piece of the pegboard top to make sure I mounted them in the right position for a flush top. I then cut the PVC pipe into 2 pieces and put a slight bevel on it using the oscillating spindle sander so it would fit well with my quick connect fitting.

After that it was just caulking the seams and fitting in the PVC coupler. I decided to anchor it with 2 screws from the inside. That was a bear to do in the tight quarters but I figured it out after a while. I cut the pegboard down to size and that was it!

Great use for some of those scraps laying around the shop!

Great job – well done with clean lines. That is a good addition… that I should build as well ! I like your idea of sealing the inside joints. Thanks for posting.

Yeah, this is a great idea and it’s much cheaper than buying one too!

Good job. I need to do the same thing, and plan to do so just as soon as I finish our kitchen remodel.
Thanks for taking the time to set up your photos. They are clean and sharp making for a good display of your project.

Yeah, that was the first thing I noticed.

One last thought…

Nice table. Why did you include two ports?

I like it , and thanks for pics and explanation. Is the pegboard just resting on the cleats? and do you find the 1/8” pegboard flexes at all? I am planning a similar box, and was wondering how strong the top piece (pegboard) has to be.
