So long story short, i crashed a needle on my new machine (voyager 17) and the timing is out. Voyager 17 is a stretch singer 2188, vertical bobbin machine. Using internet directions, i was able to sort of, but not quite do the timing. Instuctions call for a .1 mm gap - just about the resolution ofthe human eye. Where do you put the light when doing the timing? It is so tricky!
