  1. BALTIMORE AREA TURNERS November 2016 Ron Ford Don Keefer NG RNI TU TED MEN SEG

  2. “No one in their right mind does segmented turning” Segmented turning

  3. How does it compare to turning a log ? Why do segmented turning ? Allows for greater creativity Use up small pieces Much less waste Combine multiple species of wood No end grain turning Can take many forms Bowls, lidded vessels, urns, etc Why do Segmented Turning?

  4. Table saw / Miter saw / Bandsaw • Sander • Belt or Disc (with jig) • Accurate protractor / miter gauge • Thickness sander (optional) • Table saw sled (optional) • Lathe What tools are required?

  5. It is made from a stack of rings • Rings built from segments • Terminology • Segment • Thickness • Length • Width • Miter angle

  6. PLANNING, PLANNING, PLANNING…. Draw layout with CAD software like SketchUp (American Woodturner 31: Aug 16) or…

  7. Draw layout on graph paper PLANNING, PLANNING, PLANNING….

  8. Draw layout on graph paper PLANNING, PLANNING, PLANNING….

  9. Plan the number, the thickness, and species of each ring How many rings? [ringsAthruS] (19) 1. Determine max diameter of each ring PLANNING, PLANNING, PLANNING…. Draw layout on graph paper S G A

  10. 1. Determine max diameter of each ring • 2. Calculate circumference of each ring • = Diameter x 3.14 • 3. Decide on number of segments per ring * • 4 or 8 or 12 or 16 or… PLANNING, PLANNING, PLANNING…. S * * A

  11. 4. Calculate length of each segment • = Circumference / # of segments PLANNING, PLANNING, PLANNING….

  12. 5. Calculate miter angle of each segment • Miter angle = 360o / # of segments /2 • eg. 360o / 16 segments / 2 = 11.25o PLANNING, PLANNING, PLANNING….

  13. 6. Determine width of each segment/ring • What affects width? • 7. Include a feature ring? • Design the details of the ring PLANNING, PLANNING, PLANNING….

  14. PLANNING, PLANNING, PLANNING…. Or, in lieu of calculating it all….

  15. There is more than one way to skin a cat – or to make a segmented turning Cut strips on table saw Length and width of each strip is determined by your calculations The Basics

  16. Cutting, cutting, cutting…. Use a miter gauge to cut segments Choose correct angle and length for each segment Flip strip between each cut … or not….. The Basics

  17. The base? Attach waste block to faceplate Glue base onto waste block Several design possibilities for the base: - One solid piece - Segmented - Tapered Plug or - Floating disc The Basics

  18. After cutting the segments - sand them on disc sander The Basics

  19. Remove sanding fuzz Re-sand if necessary Measure length The Basics

  20. No matter how precise you’ve been…. Therefore…. The Basics

  21. Gluing segments The Basics Allen Each half at once or… All at once or…

  22. Gluing segments The Basics Tibbetts Two ** at a time

  23. Gluing segments The Basics

  24. Assembling the rings… The Basics Flatten face of each ring

  25. Assembling… The Basics Glue rings together

  26. Assembling… The Basics Flattening… gluing… flattening… gluing…. flattening.… gluing…

  27. Assembling & finishing The Basics Final steps

  28. The icing on the cake:A feature ring OR OTHER EMBELLISHMENT (Optional) Plain

  29. The icing on the cake:A feature ring OR OTHER EMBELLISHMENT (Optional) A simple band

  30. The icing on the cake:A feature ring A Greek Key

  31. Greek Key The icing on the cake: A feature ring Orientation of grain can be important

  32. Greek Key The icing on the cake: A feature ring

  33. Greek Key + The icing on the cake: A feature ring

  34. A feature ring or other embellishments

  35. The icing on the cake:

  36. the feature ring or other embellishments

  37. Open segments And Other variations…

  38. Keep it simple… And Other variations…

  39. “No one in their right mind does segmented turning” But who cares! It can be very rewarding…. Conclusion
