[ATTACH=CONFIG]540204[/ATTACH]Took her for a "spin". On this VS sm, the "vibrator" refers to the up & down vibration of the presser foot as it lifts slightly during each stitch cycle. In my case, I had the needle just entering the fabric and the vibrator thumbscrew at the bottom of its slot when tightened. An artist I am not, but I can spin tight circles and curves.
