My Poor, Poor Old Sewing Machine!

Yes, I made most of the rice bag innards last night. Still have the covers to make and about 20 reuable shopping bags to finish. My class is working on an ecology project and my part is to take recycled materials and make shopping bags. But, after all of this continuous sewing, my machine is starting to rattle a bit and I am not going to use it until I locate the oil and get it nice and oily on the inside. From the diagram, it could take from 2-8 hours for me to figure out where it all goes. I haven't used my machine much in the past few years.
