Today two of my DGKs came over. It was nice out so we went out back with tools and machines. Wilbur sat on my lap and we worked on a derelict Singer 15 - the machine had no moving parts. The machine has been cleaned and oiled but still does not turn. I told Wilbur the machine needs time out. He understands time out. He got off my lap and headed for a Singer 66. It needs oil... he got a can of oil and baptized the needle bar. The next time he turned the machine oil was flinging all over the place and some shot up out of the needle bar pocket about 3 ft. I reminded him we only use one drop on each part... He doesn't seem to get that yet. He will be 4 in November.
