Hello, I'm tuning up my stringers, filling all the holes, and some glass work. The thing I've always hated is when adding torque to the stringer bolts the cracking and the crushing of the stringer as the nuts are taking torque. The idea I'm kicking around is marking the stringer where the rail kit holes are and drilling a very tight 3/4" hole and inserting a resin covered 3/4" hardwood dowel. Then mark with the rail kit and drill a 3/8" hole threw the dowel for the stringer bolt. My thought is that when I torque the rail kit down I'm putting torque against the end grain of the dowel and not squashing the shit out of the stringer.
What do you think? Waste of time, or worth the trouble? I'm working there and glassing is going to happen anyway.
Thanks, be safe. schick
