Lap up carving and sanding dust
When shaping a workpiece with a rotary carver, and then sanding it, I like to sit with the workpiece in my lap for comfort and control. To corral the fine dust, I made this downdraft table. It rests comfortably on my thighs, with a 4" dust-collection hose coming up between my knees.
To build your own, cut an opening matching the opening in a tablesaw dust-collector hood in the center of a 3⁄4 ×16×24" piece of MDF. Round the outside corners and lightly chamfer the top and bottom edges. Then, rout a 1⁄2 " rabbet 3⁄16 " deep around the top edge of the hole. Cut a 1⁄32 " sheet of perforated aluminum (58 percent open) to fit the rabbet. Secure the aluminum sheet with 1⁄8 " wood strips held down with countersunk screws. Then, with screws and silicone, attach the tablesaw dust hood to the bottom side of the hole. Clamp on the dust hose, and you're in business!
