I was cleaning the bobbin area and took machine apart.I do not seem to be able to put bobbin parts back together. Could someone send me a picture of the maintenance part so that I can figure it out? I seem to now order of the parts but can't manuever my fingers to get the outer part and inner back together so that I can clip the black holding nobs. I do not have a manual which shows a picture of this area. I would really appreciate some help. Viking e-20, e-mail brioverton@att.net Thanks - Blessings
