WOBBLY GOBLET

WOBBLY GOBLET - off centre turning

  1. Create/cut square stock to approximately 2" x 2" x 8 inches long.
  2. Mount stock in four jaw chuck;  Move up the tail stock and engage for turning the blank to round (safer – ask Dale).  Using a roughing gouge turn the blank to round.
  3. Move tail stock away and reposition banjo and tool rest to the end of the stock. Cut the goblet interior; you can pre-drill to the desired depth. Shape the inside of the goblet to desired profile.  An end grain hollowing tool works OK here cutting from center to rim.  A bowl gouge can be used with this cut as well.
  4. Using a detail or spindle gouge cut the outside shape of the goblet to match interior profile.  Use thumb and forefinger as a depth gauge.
  5. Cutting from right to left down the curve of the goblet and from left to right remove material below the goblet.  Continue outside of goblet cut curve into a thin stem; ½ - ¾” long, and splay the cut out into the bulk material with a return curve down toward the base. 
  6. Re-chuck the stock with an offset, tilting it on the square so that the stock is at an angle to the original turning.  TIGHTEN the chuck.  Re- adjust the tool rest so that the turning profile of the goblet clears the tool rest.
  7. Turn on lathe; the goblet section will be flailing around and threatening to knock off your knuckles.  Have a look at where the goblet section and stem appear to meet solid material (there is a lot of air here).  With a spindle or detail gouge start a cut toward the base from a point approx. ¼” below where the goblet stem meets solid stock.  This allowance is to permit clean trimming between stem and stock.  Remove material to create a second stem approx. ¾-1” long.
  8. As per point 5. above splay this second stem into a base, then continue into a reverse curve toward the chuck.  Create a smooth transition at the point of interface to the upper stem and sand to finish.
  9. Re-chuck the turned assembly back to the original stock position.
  10. Shape the base.  Cut the base curve to meet the curve of the previously cut base section.  This will only occur at one side, but visible as the piece is turning.
  11. Sand the base and part off with an undercut.
  12. Apply finish.
