Make sure you have a WW patern 8mm lathe and not a mandril. You may have to ask the previous owner if the lathe used collets. The penetrating oil available over in the U.S.A. is called LIQUID WRENCH. It is thin and able to work its way into the spaces between tight metal parts. If you can’t purchase it in your area use diesel fuel. The brass rod must be a diameter that allows it to fit through the back of the spindle and contact the piece to be pushed out.
