You guys rock!
There have been so many posts with tips on solving thread tension problems and up until now, I haven't used them because my babies have been running fine.
Until last night.
I was trying some test blocks with new FMQ designs and my Janome 6260 wasn't having any of it. Stitching forward was ok, bt when I tried to go backwards, the fabric was sticking, the tension was wonky and I was getting loops on the bottom, not always, but every 1/2" or so.
First I cleaned my machine. Then I put a drop of oil in the oil well in the bobbin area, which I didn't know existed until someone mentioned it here.
No better. So, I changed the bobbin , and new bobbin thread.
No better. So I changed the needle. No better. So I changed the top thread. No better. So, I fiddled with the top tension, No better. So, I went to bed.
This morning, in better light, I noticed that there was a burr on the hole in the needle plate. So, I burnished it flat with a screwdriver. No better. At this point I was considering a service call, but lately there have been posts saying that cost > $200 , which frankly, is not in the budget.
So I pulled out the bobbin carrier and set to clean it down there again. Then I saw it! On the outside of the plastic (!!???) bobbin carrier, there were two scratches, and some burrs. So I used the open blade of a scissor to smooth that out and Presto! It's fixed! Janey is running like her old perfect self again . Yahoo!
Thanks to you guys, you gave me the confidence to keep at it until I got it fixed. Thankyou!!

Woo Hoo!! Glad to hear you were able to get Janey up and running :D:D:D

Yup, I thought I needed a new machine once but then found that there was a nick with a little piece of plastic sticking up from the bobbin housing. Woo! Way to be thrifty!

Walking away from it and looking at everything with fresh eyes helped, too. So glad you figured it out - that was a tough one!

YAY!!!!!! I'm like you --- hate to spend money for somebody to fix something I might fix -- after all, if we give them $$ then we have less for the good stuff - fabric and chocolate!!!!! :) Glad you got it figured out!

Wonderful. This place can be a lifesaver.

To smooth burrs and nicks try using an emery board first. I keep a piece of very fine grit sandpaper in my sewing room. I can usually find a solution to any machine problem by googling the question. It's amazing how many times Google gives me this board address!

Way to Go!

Awesome! I have learned so many great things here!

Glad you got it fixed, doing the Happy Dance!
