After the sawmill's abandonment in 1839, the original sawmill complex buildings rotted and disappeared. However, timbers cut by the original mill survived in buildings on Mackinac Island (Mission Church and Mission House, built in the 1820s and still there today). Saw marks on these timbers could be used to reconstruct the mill machinery so as to closely resemble the original. The marks gave restoration experts information on the rake of the saw's teeth and the saw's operating speed. The wood is fed into the blade at 1/3 of an inch per stroke, and the infeed motion is powered by the pitman arm that powers the saw's vertical movement.
