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.
