I just got my Sew-Classic order today. I put it in last Friday. Wow! I ordered some Class 66 metal bobbins. They are beautiful. They look to be one piece, not the 3 piece ones normally found. Very smooth plating.
I haven't used any yet, but if they work as good as they look I'm going to order some more.
Does your machine buzz, hum, groan and struggle to go?
Does it do all that then suddenly take off like a scared rabbit?
Do you have one of those universal black rubber band belts on it?
Then take it off and put a real sewing machine belt on.
I have had several machines do this to me. And each ran so much better with a proper belt on it I wondered if it was the same machine. The last was my silver SEWMOR 404. I didn't have the proper belt for it until my order got here today and when the new belt went on, oh what a difference.
