Thanks Prism - the bobbin I needed to wind was from a kenmore and my other machines are Singers. After 4 hours I got at least one machine to do what I wanted! I'm sorry for being grumpy, but this was a very upsetting event. I'm happy now, the quilt is done and at least one machine works!
I found a bag of 13 rubber tires for bobbin winding! I purchased 15 of them on an ebay auction YEARS ago when I needed one for my Singer Treadle machine, so they were in the drawer of the treadle.
5 sewing machines sounds like a lot doesn't it....I teach and turned a room in my home into a studio to teach sewing. I already had a few machines from family and I purchased a $25 and a $20 one for teaching.
Thanks for the help!
