Abstract
Centering a log by determining the location of a selected axis through the log relative to a fixed replicate axis. The log is pinned and each end is provided with double pivots. Pivoting the log about one pivotal axis spaced from the replicate axis determines a pathway around that axis. Pivoting the log about the other pivotal axis sweeps the log end and, accordingly, the selected axis across the determined pathway. The selected axis is positioned on the pathway by pivoting the log about said other axis and it is positioned at the replicate axis by pivoting the log about the first pivotal axis.
