The friction of the shavings or paper causes the alcohol to evaporate, and the shellac melts into a smooth finish. Friction heat will melt it into a glossy final topcoat. With the workpiece spinning, use shavings from the turning to burnish the shellac into the wood. I increase the speed for parts thinner than 1/2″, and I decrease the speed for turnings over 2″. I use 1,800 rpm for any spindle between 1/2″ and 2″ in diameter. You need quite a bit of speed for this process to work. When the wood is completely saturated, start the lathe and burnish the finish with either shavings from the floor or a small piece of paper towel. With the turning mounted in the lathe and stationary, I brush on the shellac. cut, which is about right for a simple padding application on the lathe. cut,” which equates to 8 pounds of shellac dissolved in one gallon of alcohol.Ī full-strength solution like this is far too viscous for our needs and must be diluted by mixing one part full-strength shellac to three parts alcohol. This will yield a super-saturated solution - what finishers call an “8-lb. You can accelerate the process slightly by placing the bottle in a sunny window or outside on warm summer days. I cap the container and let the flakes dissolve over a period of 12 to 24 hours. I mix a small amount of dewaxed shellac flakes with enough denatured alcohol to cover them. This “old school” shellac will give much better results at the lathe. While you can buy premixed liquid shellac at a hardware store, I prefer to use dry shellac flakes that have to be dissolved in denatured alcohol. It also dries incredibly quickly and is food safe. Any finish will stick to shellac and vice versa. Shellac is a splendid traditional finish for spindle turnings, bowls and boxes. cut of shellac liberally onto a spindle or other turning while In that spirit, here are some of my choices for quick, simple finishes to try. So turners tend to like finishes that beautify and protect their handiwork, pronto. One of woodturning’s attractions is that a beautiful object can be turned in a relatively short period of time.
