In my small shop, my tablesaw doubles as an assembly table. To protect the saw’s surface when I’m gluing or staining, I installed a heavy-duty vinyl window-shade on the end of the extension table (about $20 at hardware stores). The shade is easy to keep clean. Glue doesn’t stick to it and stains wipe off with mineral spirits. When I’m done, a simple tug on the end retracts the shade.
