How to build a log cabin that won't settle

I researched building a log home for years before I settled on the Skip style Butt & Pass method taught by the Log Home Builders Association. Almost every style I came across needed special hardware and spaces built in above door frames and windows. Special screw jacks may be required for other styles to lower the roof as the walls shrink. LHBA claimed (correctly) that none of this was needed for their method. This video attempts to explain why. This "secret" was the only thing I couldn't find an answer to before I took the class. This secret is also the reason why anyone (with enough grit) can build an LHBA log home, even as a "first time builder" like me.
