Good news! I'm winding bobbins like a champ! Local repair shop used some tools to break the inner wheel lose and replaced the rotted rubber wheel on the bobbin mechanism all for $2!
I think the manual I listed before is my machine, or at least really really close. They will clean and oil the entire machine for $70. I know this machine probably isn't worth that, but I love how it looks and it was my Grandmother's, so I will probably be going back next week to have them do that. Will that help the stitch to be more consistent? It could be user error, but it seems like the stitches vary when I'm sewing a long line.
You have all been so helpful!
Thanks, Ann for getting me going in the right direction. The Centennial 2 search is what located the link I posted. You rock!!!
