Hi this is a documentary video about the process of making violin. They ue wood of course for making violin and they draw the shape and then cut then violin shape out, then they shave it to reach the right curve and right thickness of the up and down part of the violin. For the sides of the violin they use thin strips and putting on the water then pushing against a tool and curve it then stick it to the frame to save its shape. They only use glue for making violin. They glue and stick part and hold them with the tools like you see.
