Drill your sanding discs to increase dust draw
Shortly after buying a large quantity of sandpaper discs for my orbital sander, I upgraded to one with superior dust collection. But, the dust-collection holes on my new sander didn't align with those on my old discs. Not wanting to waste unused sanding discs, I came up with this solution for retrofitting the old discs to the new sander.
First, build a scrapwood frame to hold the sanding discs stacked together, as shown. Then create a hole template that matches your sander—I traced the holes from a sanding disc that came with my new sander on a piece of scrap hardboard. Press the template over the stack of discs and drill through. —Michael Harman, Beavercreek, Ohio
