The first and second saddle support include arcuate base plates that are arcs about a log axis with an arc radius that is substantially equal to the log radius of the log to which the base plate and extends outward from the convex side of each base plate. The saddle member is pivotally attached to the posts of the saddle. The saddle member extends 180 degrees around a rafter or moist and has a saddle member axis that is substantially perpendicular to an axis of a log to which the saddle supports are attached.
