the blower is driven by direct coupling with motor. first off i want to tell you i’m really sorry for your loss. i guess i will just stick to honey. even though you politely asked your toddler what he wants for lunch, as you start to make the cheese sandwich that he requested, he changes his mind, maybe ham or egg. he kept me up to date with every step as it happened and was great to communicate with. you can just put the graham crust on the bottom of the pan or you can also come up the sides.
