Since my Paint Booth works for collecting dust from sanding, causing the filter to clog up quickly, I decided to build a Downdraft Table.
It’s about 24” x 24” x 4”. The box is 3/4”, 1/2” plywood bottom, 1/4” plywood for internal bracing, and of course the top, Peg Board.
I ganged cut the 1/4” plywood. Cut rabbets in the 3/4” sides for the 1/4” and 1/2” plywood braces and bottom. Some people might want to make the bottom funnel shaped for real down draft.
I still have to cut a hole for the vacuum hose.

I wonder if all of the internal structure will impede air flow? Are you hooking it up to a DC or a shop vac?
Here is the one I built for my table saw extension:

I hope it doesn’t impede too much.
I’ll use my shop vac until and if I ever get a dust collector.

If you have trouble with not enough airflow you could try closing off the surface area except for the area immediately around what you’re sanding. Painters tape would probably work in a pinch.

Since you’ve used pegboard you can use golf tees instead of tape to close off the unused area. It really doesn’t take long to do and when you’re done flip it over and scoop them up. I prefer this for mine since the tees are reusable.

Creative but I think all those supports and half moon cuts were overkill.
Wished I had one. LOL

You guys might want to consider dowels, instead of 1/4” plywood.
That would leave a lot of area open. That, I suppose, would be less impedance to air flow.
And as for covering the excess holes, newspaper works well too. Oh wait, newspapers are going away. The desert has plenty of plastic bags out here.
