Members Yetibelle Posted April 20, 2017 Members Report Posted April 20, 2017 There are a few 29k restoration links out there. http://northants-restoration.blogspot.com/ This one is a word doc, with pictures not sure if the link will work in here? https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=14&cad=rja&uact=8&ved=0ahUKEwiq2MSlubPTAhVKPiYKHUuJDMIQFghoMA0&url=http%3A%2F%2Fneedlebar.org%2Fmain%2Frestoration%2FSinger29K13.doc&usg=AFQjCNEA0DvpI_cgnioBfZRNQbNTqgeKbQ Quote
Members shoepatcher Posted April 20, 2017 Members Report Posted April 20, 2017 It has to do with restoring the "figure 8" on the end of the bell crank. The lobes wear down on each side and that causes the stitch length to shorten. If someone is a competent welder, the lobes can be welded up with a Tig or Mig Welder and reground with a Dremel and you are almost good as new. I have 30 plus bell cranks from Adler and Singers that have to be welded and reground on the lobes. That is a project for when I retire. That is normally the only thing to go wrong with a used bell crank. glenn Quote

Members Constabulary Posted April 20, 2017 Members Report Posted April 20, 2017 I once restored a 29K1 so this thread may be useful for you: Quote
