Guitar building is not necessarily a pleasurable experience. The craftsmen is always on the edge. One wrong move of the hand, one bad thought or one small distraction and disaster happens. Wood is not uniform. It is moody, it can be deceptive, sometimes hiding faults until the very last moment of finishing and you have to start all over again.
Handwork can torment and it can elate.
No matter how hard the craftsman tries or how experience he is he knows that perfection can never be achieve for the simple reason that humans were not created to be perfect. Our natural condition is that of error and mistakes. It is not necessary. We have all heard the boasting of computer controlled machine operators that micrometers can be used to demonstrate the precision of their products. Frankly, I find this ridiculous.
