Description:Alexander McCracken, 85, builds instruments in his spare time.
The 85-year-old retired carpenter's hands are gnarled from years of sanding, sawing, and hammering away at building houses. But that hasn't stopped him from taking up a new craft. McCracken builds instruments, handcrafted with American woods such as mahogany, cherry and pine.
He can't play them, so he asks others to demonstrate the sounds of his creations.(1:21)
