Hi TonyT and TexanTomcat2.
I was looking through old posts of mine to close out one part found and still looking for others when I found this.
Thank you for your responses – I never saw them at the time. I must have gone into one of my intense spells of occupation by other things 🙂
So a late thank you for your help. I did manage to sort the pivot bolt and bobbin nut problem.
Cheers.
