I have discovered the facebook profile of Kiyoto Tanaka, a Japanese luthier who builds romantic guitars and other instruments. Kiyoto Tanaka has documented the construction of his guitars in very detailed videos. It looks like magic how he uses his Japanese woodworking tools to take some wood and make a beautiful guitar out of it.
But first I recommend the following video with a little box-harp and a 19th century guitar:
The lullaby by box-harp and 19th century guitar.
Plays Sor with the guitar of own manufacturing.
The guitar construction videos show many steps of the construction of the guitar mainly using Japanese hand tools in real time.
Martin Seeliger has started to build steelstring guitars in Germany in the earl 1980s. Today his brand Lakewood Guitars is known as a source for great guitars for fingerpickers, and many great artists are playing Lakewood guitars.
On the homepage of the German guitar magazine Akustik Gitarre you can find a very interesting video with an interview with Marting Seeliger (in German only), and during the interview some interesting steps from the production of Lakewood Guitars can be seen.
