Who's Up For A Challenge?
The challenge for October will be to turn a three-corner box/bowl using Tim Verbeke's September demonstration as a guide!
The challenge for September was to turn a finial to achieve the highest length to diameter ratio of the shaft. The turner who obtains the highest ratio will be awarded an additional ticket for the next quarterly challenge drawing and bragging rights.
- The finial will have a base with a diameter no less than three times the largest diameter of the shaft. The base will be large enough to support the finial standing vertical.
- The finial will have a tip with a diameter no less than two times the largest diameter of the shaft.
- There will be NO beads or any other entity between the base and the tip – ONLY shaft.
- The turner will place a thin mark on the shaft just above the base and another thin mark just below the tip. The distance between these marks will be the length of the shaft. The marks may be done with a pencil, ink pen, or Sharpy.
Determining the Ratio:
- The person evaluating each finial will measure the length of the shaft from mark to mark to the nearest millimeter.
- The person evaluating each finial will measure the diameter of the shaft to the nearest millimeter. The diameter of a tapered shaft will be the average of the largest and smallest diameter of the shaft.
- The ratio will be determined by dividing the length of the shaft as determined above by the average diameter of the shaft as determined above.
This challenge is to demonstrate skill only. Other than smoothness of the shaft, base and tip, embellishments will not be given consideration. No boxes, hollowforms, or other turnings are to be done.
Tip: The longer the shaft, the easier it will be to get a high ratio.
Have fun folks,
