In 1926, wood turning represented two-thirds of industrial activity in the canton of Moirans. In Martigna in 1930, of 300 inhabitants, 30 were wood turners or farmer/wood-turners (D. Schwint, 1997). Like in Martigna, the small sawmills that used the lake’s spillway to action the paddle wheels were turned into wood-turning workshops as soon as electricity became available.
