Simply soak a washcloth in water and ring it out a bit so it’s not sopping wet. Put the damp washcloth on the affected area. The water will wick through the wood, and that’s fine. Now, with your iron on its highest setting, place it on the damp washcloth over the affected area, and make small movements back and forth and in circles. Press down firmly and continue until your wash cloth is dry. It won’t take long to evaporate. At this point, the wood fibers are absorbing the water and should expand back to where they were originally. Continue this process and repeat by adding more water until the dents rise up to be flush with the rest of the material.
When cutting full sheets with my circular saw, I use plastic shelving units as sawhorses. The height is just right and by using three of them, I can make cuts in any direction and the plywood is fully supported. And because the shelving units are made of plastic, I can cut right into them without worrying that they’ll damage my saw blade. Plastic shelves are available for $20 at home centers. — John Tinger.
