What is the acceptable moisture content for the timber handles?

Typically between 8% to 15% to maintain dimensional stability and prevent shrinkage.

Which defects are strictly prohibited in the handle timber?

Cracks, large knots, cross-grains, and fungal decay are prohibited as they severely weaken the handle under torsional loads.

Hardwoods with straight grain profiles that can withstand high twisting forces without splitting.

Practical Notes

Ensure timber is properly seasoned to the specified moisture content to prevent the metal tang of the auger from loosening over time.

Straightness of grain is critical; cross-grained wood will easily snap under the torsional stress applied during boring operations.

Handles must be sanded smooth to prevent splinters during manual operation.
