Posted to a copy of the Youtube video by ArtMad1:
“An intricate hand-cranked machine made entirely of wood and glue (no metal or other materials). It was designed and built by my friend Del, using many different woods and incorporating a variety of mechanical motions. He has made several other wooden machines, but calls this latest one his crowning achievement. Del was born in July, 1937. If you would like to communicate with Del directly, his youtube channel is: http://www.youtube.com/woodificood
Also of interest: a feature article about Del in the magazine Scroll Saw Woodworking & Crafts (summer issue 2011). Web version here: http://www.scrollsawer.com/features/mechanical-marvels-in-wood.html”
