My wonderful wife bought me a lathe for Christmas I am trying to learn how to use the skew chisel, I have practiced roughing out blanks with a skew with success, turning a tube for turning spindles, everything has been fine until I have tried to turn a bead with the short end of the skew--disaster! All I do is catch the tool and take a big hunk out of the blank, I have tried lowering the tool rest, raising the rest, closer, futher, changing the angle on how I hold the skew, changing the speed, nothing seems to work for me. What is the secret?
