Mounted the DC stubs to the bottom and then attached the bottom with TBII and screws.
Using textured one side 1/4” Masonite with the smooth side in for the sloped pieces.
I taped the transition from the slope to the bottom on the inside so the debris doesn’t hang up at the transition. And I caulked the angled joints at either end. The Masonite is attached with screws only, so I can get back in there if I decide I need some kind of baffle.
Next is to mount the table between the TS and my work bench.
