My wife has an industrial sewing machine used for quilt making. Over the last few days it has started to act up. Last night and tonight I have been working on the machine adjusting the timing rather than doing any of my own project work. Not complaining just explaining.
One thing I will say is that sewing machines are bloody marvelous. The exquisite mechanical linkages, gears, and manipulators are ingenious. But also very finicky. Having to get the thread tension, and timing of the needle and hook just right is a pain. You have to remove an access panel and then loosen three screws to adjust the timing of the hook. The hook needs to pass through the scarf of the needle by just a few thousands of an inch and in a narrow angular range. And when you tighten the screws, it changes the position. Very frustrating. Too close and it “pings”. Too far and the thread gets mangled. Get to work on it more tomorrow. What joy!
What I don;t get to do is play with the new Sparkfun parts that came today as well as the PicKit-3 that came from Digikey yesterday. Perhaps I will get time on Sunday.
