This simple jig makes laying out circles a breeze. Drill a 1/8-in. hole through every inch mark on a ruler or yard-stick. To draw a circle, place a pin through the number “1” into the center of your board. Add 1 in. to the radius of the circle you wish to draw, and insert a pencil into this number. Using the pin as a pivot, rotate the pencil to mark the circle. — Edwin Constantino. How to Cut Curves in Wood
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.
