Sanding-Drum Dust Collector
Whether you add sanding-drum dust collection your drill-press table or to some other table, here's the lowdown on how to do it.
Before applying the finish and installing the mini-track, lay out a 21⁄2 "-wide stopped channel that intersects the 3 1⁄2 x 3 1⁄2 " cutout in the table, where shown on the drawing at the bottom of this page. (Lay out the channel to the right or left of the center cutout, depending on the most convenient location for your shop vacuum.)
Then adhere scrapwood guides to the table with double-faced tape, aligning them with the layout lines. Now rout a 5⁄8 "-deep channel, as shown below.
Note: If your table doesn't have a cutout and insert, drill 3⁄8 " corner holes, and jigsaw a cutout. Then rout a 3⁄8 " rabbet 1⁄4 " deep around its edges for a 1⁄4 "-thick insert.
Using a pattern bit guided by scrapwood guides, rout a 2 1⁄2 "-wide stopped channel 5⁄8 " deep in the bottom of the table.
Change to a 3⁄8 " rabbeting bit, and rout a 1⁄8 "-deep rabbet along the edges of the center cutout and the channel, as shown below. Stop the rabbet where dimensioned on the drawing, bottom. Cut two 1⁄8 " hardboard covers to fit the rabbeted openings, and glue and clamp them in place. Apply a finish, and install the mini-track. Using the holes in the shop-vacuum dust port as guides, drill screw holes, and fasten it in place.
Rout a 3⁄8 " rabbet 1⁄8 " deep along the edges of the 3 1⁄2 x 3 1⁄2 " cutout and edges of the 2 1⁄2 "-wide channel, stopping 3" from its end.
