Usually I don't recommend you to take the violin apart because you may disturb the bridge and the sound post if you are not careful, you may snap the strings or break the wood but if you insist on taking it apart try going to a specialist and ask him/her to help you. DON'T TRY TO TAKE THE VIOLIN APART AS YOU MAY HURT YOURSELF IF THE STRING SNAP OR IF THE WOOD BREAK!!! So try to go to someone experience okay ^_^.
