ABSTRACT OF THE DISCLOSURE An elongated base is provided including elongated guide structure extending therealong. A router assembly is supported from the guide struc- ture for guided movement therealong in a predetermined path and the base includes support structure for supporting an elongated log in position extend- ing along a center axis generally paralleling and adjacent the aforementioned predetermined path. The router assembly includes cutting blade structure operative to form a convex generally semi-cylindrical surface on the adjacent side of a log supported from the support structure and the latter is operative to engage and support the log from the semi-cylindrical surface formed thereon after the surface is formed and the log is rotated 180 degrees about its longi- tudinal axis with the log then supported in position for forming a second semi-cylindrical surface on the side of the long then opposing the path of movement of the router assembly with the second semi-cylindrical surface having an axis of curvature coinciding with the axis of curvature of the first formed semi-cylindrical surface. The cutter blades of the router assembly further include blade portions operative to form shallow keyways in the central por- tions of the semi-cylindrical surfaces formed thereby.
