After getting my Singer treadle sewing machine back from the spa (repair shop for cleaning, oiling and maintenance) I realized that I needed to tighten up the belt. I hadn't done that since I installed a new one a year and a half ago.
I just opened the staple, cut about a 1/4" off one end of the belt, poked a new hole in the belt and reconnected the staple. It wasn't difficult to do, but did take longer than I expected because I don't have the proper tools. However, I made do with what I had and stuck with it, and was delighted to be successful!
The new belt made it easier to wind the bobbin, and it was going along well until I came to a knot in the thread. Can you see that knot where the seam ripper is pointing??!! That will not go through the vibrating shuttle bobbin at all, so I had to cut it at the knot.
But I had wound enough thread on the bobbin to get back to piecing some scraps....ahhhh... so fun!
