Save Time Sanding
Do more accurate work by ganging up curved wooden pieces
The next time you have to sand two or more curved wood parts, try this shortcut: Clamp the parts together in a bench vise, making sure that their ends and edges are flush together. Then, chuck a sanding drum into an electric drill and use it to smooth the contoured edges. Be sure to keep the drum moving back and forth at all times. If you stop in one place, you'll create a depression.
Unlike other timesaving tips, this one will actually increase the accuracy and quality of your work. This "gang-sanding" technique can also be used with a belt sander to smooth several straight-edged boards at the same time.
