The off-centre tree is a relatively simple idea that produces quite a striking effect. Mark the end of the piece with the two centre holes and then to draw a circle on one end and mark three points around the circle at 120o apart. By eye is good enough. Mark each of these holes with a different colour. Then turn the basic shape and using the three different colour markers make 12 lines along the body from about half way along to near the end of the conical section, evenly spaced (by eye again). The look is produced by moving the turning point at the head stock end to one of the coloured points and then using a skew chisel cutting ‘V’ shaped grooves at the points on the matching coloured lines, these grooves being deep enough to get about 130/140o (just over a third of the way) around the circumference. Use sand and seal to cover all the surfaces (to avoid bleed), apply the paint into the grooves and then sand down to leave only the cuts coloured.
