Found solid metal shaft approx 7/8" diameter (steering shaft from Allis Chalmers WD tractor). Cleaned shaft and used to form ruddder leading edge. After considerable difficulty, fitted and riveted rudder leading edge. Installed rod ends. Torqued jam nuts on bottom and center rod ends. Installed rudder counterweight. Removed remaining plastic. Spent most of the time scratching my head...more than usual.
