Jagged Fret Ends

[Moth]

clip the fret tangs like you would when you do binding so at least the tangs dont pop out..Also this gives a finished look to the FB as you need to fill the side of the fret slot.

+1!

besides clipping the fret tangs you can also pre round the fret ends off the guitar.. I saw this done on Erlewine's fret video..

An easier method is wait until all your frets pop again on your previous guitars then start building. Then you know the shop is dry as so your wood will be too. Your guitar can only expand at that point, expansion is less damaging than contraction and your fret end shoud not pop anymore..

Or we should all move to the southwest where it is dry all year long..
