I made a new hinge rod for the foot joint, because the existing one could not be straightened.
When padding flutes we have to use little paper pieces called shims to get the pad to stick out the correct amount. We use partial shims to get the pad to seal evenly on the very uneven tone holes. We then bake seats into the pads using what we call the "Easy Bake Mail Box."

I broke a screw in the spud out of one of my flute pad cups, and we didn't have any yamaha spuds in our parts bin. I made a spud on the lathe, used a dremel tool to remove the original spud, and soldered the new spud into the pad cup.
