Help! My Martin is Cracked!

When I first graduated from repair school and I started working at a box office music store, and after a few weeks there I started seeing complex repairs coming in since there was finally a tech that can do more in depth repairs in the store. This Martin came in, with a crack measuring almost 13 inches if my memory is correct, and the customer was devastated that it was the end of his guitar but he heard if any one could fix it, I would be his best bet. After some hide glue, clamps, and strategic finish work, we sent this martin home looking good as new and with a fresh setup, the customer was exatatic and was so happy with his guitar once again.

After the initial repair, I let the instrument be humidified and the thin line slightly blended in with the wood grain, and dulled the finish and was perfect.
