ehrouz Mohammadi, “Daf and its feasts in Ghaderieh’s Tekyeh” mentions that the outer thickness of arch where studs are located, [is] between one to one and a half centimeters (Mohammadi, 2001: 12). The thickness of arch should be gradually reduced from the installation place of rings to skin (Avazeh of Daf) to create a high volume, clear sound from Daf; also, the connection of arch to skin should not be less than one millimeter, because in this case the skin will be torn due to the sharpness of the wood (Mogharab Samadi, 2009: 79-78). The thickness of wood on the skin side is about two to three millimeters (Tohidi, 2002: 79).
