wonderful. I was just wondering about the gauge, seeing it in the booklet, at the far end of space-time. is it a metal triangle , thick as the space between the two fingers of the presser foot, with an hole at the right highness of the needle eye?
yesterday I was encouraged to make another proof and I had the boldness to unscrew the needle...
now after twenty attempts it seems right. it makes green stitche. but when it met the fabric, double light flannel, I heard a sort of little squeak , that alarmed me.
but the two needle, upper and circular, don't touch each other. is it possible the point of the needle is a little dull?
I search to take photos
my machine is very similar to your, but mine is more.... dirty!
