Hi, often when I oil using the Bernina oil dispensers or the Singer oil dispensers I end up making a mess. Sometimes the drop misses a hole so I have to do two or three drops; only one of them doing any good :hunf: (kind of like that old kid game of dropping clothespins into the jar-HaHa). Other times, one drop seems like an overkill. I went to my local drugstore hoping I could buy a hypodermic needle but was told I need a prescription. What device do you use to control the placement and amount of oil going to your machine and where can I get one? Thanks in advance!
