Wzcrafts, a picture is worth 1000 words, so here are a few that will clearly show what I'm dealing with. I threaded the machine tonight with #69 bonded thread (top and bottom) and mounted a #18 needle, hoping to get the top thread to pick up the bottom thread. Well....it did not pick up. After looking at each shuttle closely, I discovered the one I was using has a worn point. If you look at the marked up images you will see what I am referring to. My next plan is to remove a good spring from a bad point shuttle and place it on the best of the three and see what happens next. Unfortunately I only have these three shuttles which came with the machine and will need to purchase some new virgin ones.
