I have a 60s Touch n Sew and I am not sure if it's me or the machine! It will work angelically for a couple projects and then it turns into this demon machine. I just took it in last December for a timing adjustment. It sewed some curtains and some other scraps perfectly. I used a ruffler foot on it, now I have a suspicion the timing is off again. The bottom stitches just don't look or feel exactly right. Not to mention, it's jamming frequently.

I have an Elna Lotus from the the 70s that I love dearly. I have not had any issues with sewing through any material. I'd like to keep using the Singer because it is bigger and has more function than the Lotus. Plus, it was my grandmothers. She used it everyday. I wish I could ask her if she ever had issues!

Are these Singer models notorious or am I just that bad?
