Both my Brothers (cheap computerized ones from Walmart - a CRE-5000PRW...I think that's the number, and a SE-350) have developed a distinct rubbing sound when I let off the pedal and the needle comes to a stop. Now, granted, they haven't been professionally serviced in a while, but I have taken apart the SE-350 recently, cleaned it really well, and oiled the moving joints with sewing machine oil, both above and below the needle.
The sound is similar to balloons rubbing against each other, only lower in pitch. It started out soft and it's gotten louder and louder.
I can only assume I've missed something that needs to be oiled? Has anyone else ever heard of this problem? I've listened closely and tried to determine exactly where the sound is coming from, and I want to *guess* that it's in the joints directly above the needle, about 3 inches up, but I'm not sure. If I oil the joints where I think the sound is coming from, the sound stops for several minutes of sewing, but then it starts up again... Since I've pretty much done what they do when you pay to have a machine serviced, I really don't want to pay the $70 to have it serviced at the local sew 'n' vac shop. Of course, if it's a problem I can't easily fix, into the shop it will go!
Thanks for any advice.
ETA: Okay, I left the machine alone for a couple days because I didn't want to deal with it. I've been sewing now for about half an hour and the noise is gone. It's sewing beautifully - like brand new. So I guess I somehow did something right servicing it, and I guess as far as the rubbing, the oil just needed time to soak in. (That's what hubby says, anyway.
