Hi everyone, I just finished resetting the neck on this nice 70s Martin, and repaired a large soundboard crack. In this video, you can see how I use magnets to find the exact center, and act as clamps in gluing the spruce cleat. The video says it all, so enjoy! I wanted to do this in one take, with no edits, but my iPhone ran out of memory, and I had to do an edit towards the end! Oh well. Thanks for stopping by!
