Bernina Jubilee 1953
Hello everyone and thank you for accepting me on your forum. I have this Bernina machine, a model Jubilee from 1953 that my grandmother gave me. The machine stood still for ca. 40 years, but all is still intact and all parts are moving, except the lower knob that I marked red (picture from Google). I bought new rims and oiled the inside well but this knob and its mechanism are not cooperating. I’m afraid to use force on the internals. Is this a known phenomenon for machines that have been standing for a while? I would appreciate any ideas and advice on how to proceed. Thanks in advance and a lovely evening - Shachar.
P.S.
If there are other aspects that I should examine in such an old machine, before starting it, I would of course like to hear it. For example, I checked the electrical side, but only at the level of the cable that connects to the electrical outlet: it has no cracks and it looks fine on the surface. But are there other things I should check? Thanks again.
