I have just written about the guitar construction movies by Tiyoto Kanaka which show the construction of a guitar in many detailed steps.
Some time ago I have found the following video which shows the construction of a classical guitar using time laps in little more than 5 minutes.
The guitar was built within 10 days in a private training course by Rober O’Brian from a kit by LMII.
If you ever wanted to see how a classical guitar is constructed from wood and glue you should watch this movie. This is a good introduction for the detailed movies by Kiyoto Tanaka.
