If the guitar is not vintage, but so worn out that further repair is impractical, it can be redone do it yourself into something else. The most obvious, of course, is the column. But this option is not necessary. How about a suitcase? So the author of Instructables thought under the nickname RowanCant. And made an interesting homemade.
The master removes the strings from the musical instrument, and then cuts the bar from him. Cutting, biting strings, burning them out if they are nylon is not allowed - they are very tight and can injure. Moreover, it is impossible to saw off the neck with tensioned strings.

Saws the guitar so that it is divided into a suitcase and a lid:
Repaints (this step is optional):
Attaches the cover with hinges, closes the hole in the deck from the inside with a wooden plug, adds a handle:
Parses the latch from the empty bottle, remakes it into one:
You can remove only the strings and leave the neck. Place the handle on top and the rollers on the bottom. You will get a suitcase like a tourist one, only the handle will not be able to move.
