I re-read Rain's blog http://vssmb.blogspot.com/ all about 201-2 bobbin case maintenance. I also read his post about removing the hook. I made sure that the bobbin case was seated correctly and, for good measure I took the hook out and checked that the retaining clips were tight. Yup. All good. Then I looked at the position bracket. I had taken it out to get the hook out anyway. Something did not look quite right to me. I compared it to the WIP (work in progress) 201 and sure enough, the position bracket was bent.
I gently bent the piece back into place but I decided that I wanted to use the un-damaged bracket on the Centennial....in case I sell it.
I put that in and the issue was solved. I finished cleaning the machine and tested it. Very nice stitches. And it ran like a top. So fast... so very fast. And quiet. This is a really nice machine.
Cosmetically it shows its age. It was a school machine and came with the 401 four drawer school cabinet. You can see initials carved in the bed of the machine. I think there are about 4 or 5 sets. Otherwise it looks ok. It shines up nicely. I hope to take some decent photos, just in case.... My camera is sick. I think I have dropped in one too many times.
I have two other 201-2s. One is not usable and the other is "mine." That machine has the first motor that I rebuilt and so I have decided to keep it. I think....but it is having tension issues. It would sew fine at "normal" to slow speeds but if I ran it fast at all, the tension would be all wrong. Stitches would be ugly with loops on the bottom intermittently. I knew something was wrong.
I took out the bobbin case and oiled and cleaned all around in there. It was pretty clean. I examined the needle plate. AH HA! A big old burr on the needle plate
Out came the bobbin case again. I figured it had to be something to do with the bobbin tension. I just did not see how the top tension could loosen that easily and intermittently.
The tension felt fine when I pulled on the thread. It was a little raspy, but the tension itself felt perfect.
I dug around in the spring with my dental pick. Voila. LINT!!!!!
So then I went back to square one. the thread would pop out of the first thread guide. It was not tight to the body of the machine so I gently tap tap tapped it into place. No better. By now its time to go to visit some friends. I had to give up. Only temporarily. The rest of the story......tomorrow.
