Abstract
A wooden member fabrication method which, by a simple process, can enable greater stability of shape subsequent to processing and uniformity of color tone. A wooden original piece with a long form has a hole thereinside which extends in the length direction. Corner portions are chamfered and radial direction thicknesses are substantially constrained to a certain range. An outer periphery of this wooden original piece is compression-deformed in directions toward an axial central portion and the outer periphery is thus made an arc surface. Because of the chamfering, radial direction thicknesses of the wooden original piece are constrained, and differences by location between compression ratios can be suppressed.
Claims20
A wooden member fabrication method comprising the steps of:
- providing a wooden member original with a long form and including a hole thereinside which extends in a length direction, the wooden member including a cross-section perpendicular to the length direction which is substantially a rectangle of which corner portions have been chamfered;
- and
- compression-deforming the wooden member original in directions toward a center of the cross-section, for making an outer periphery of the wooden member original an arc surface.
A wooden member fabrication method comprising the steps of:
- providing a wooden member original with a long form and including a substantially rectangular cross-section;
- dividing the wooden member original into two segments by a plane which passes along a length direction through a substantial center of the cross-section;
- forming, at a divided face of each of the two segments, a channel which extends along the length direction;
- chamfering corner portions of the wooden member original along the length direction for constraining thicknesses of the wooden member original to within a predetermined range;
- and
- pressing and joining the two segments such that the divided faces are matched up.
A method for fabricating a wooden member for covering a vehicle steering wheel, the method comprising the steps of:
- providing a wooden member original with a long form and including a hole thereinside which extends in a length direction, the wooden member including a cross-section perpendicular to the length direction which is substantially a rectangle of which corner portions have been chamfered;
- and
- compression-deforming the wooden member original in directions toward a center of the cross-section, for making an outer periphery of the wooden member original an arc surface.
