Woodturning is a time consuming discipline, with a little ingenuity you can make a duplicator for your wood lathe to speed things up! If you repeatedly turn the same profiles for table legs, baseball bats, etc. This design might be right for you. It uses a small amount of plywood, some hardware and an angle grinder. I used a dewalt with a King Arthur chainsaw wheel. There are some expensive duplicators out there, such as the Vega. Save your money and become more skilled at the same time by creating your own duplicator.
