Friday it is! I mean you WILL be.

This is exactly why I'm not signing up for the 2014 Buy No Guitars challenge. I'll just wait until next December and find something awesome. Beautiful guitars you have there. If that lottery ticket pays off, I'll be in touch…

I'm a fan of C#m, coupled with an A. Allows for that nice major/minor solo thing.

A mild steel truss rod will expand and contract at a rate of 0.0000073 inches (7.3 millionths of an inch) per inch per degree Fahrenheit. If the guitar was at 72 degrees Fahrenheit and cooled to -10 degrees Fahrenheit that would be an 82 degree change in temperature. This would make the truss rod contract 0.0005986 inches per inch of length. A 21-fret 24.75 inch scale guitar neck is will typically measure 17.39173228 inches from the nut to the 21st fret. That would make the total shrinkage of the truss rod 0.0104107 inches over its entire length. I’m not certain what threads are used on MIJ Squier truss rod nuts, but they are likely M4 diameter x 0.7mm pitch or M5 diameter x 0.8mm pitch metric threads. An M4 x 0.7mm truss rod nut will move 0.027559055 inches per revolution and an M5 x 0.8 mm pitch nut will move 0.031496063 inches per revolution. That makes the 0.0104107 inches of truss rod shrinkage equal to 119 to 136 degrees of truss rod nut rotation or between 1/3 and 3/8 of a turn, depending upon the pitch of the truss rod nut. The neck wood will shrink as well, but only about 0.0000017 to 0.0000027 inches per inch per degree Fahrenheit or a total of 0.0024244 to 0.0038505 inches over the length of the truss rod. Easy answer…yep, could have snapped from the cold...and...
