Hi,
I've been using my mum's Singer Zig-Zag Model 457 and have inadvertantly stripped some of the teeth of the top vert shaft bevel gear. I have found a supplier that can get me a new one, but I don't know how to get at it to replace it.
Firstly, is this the right forum to be asking this type of question?
Secondly, does anyone know how I get at the gear to replace it?
And finally... if anyone knows how the teeth were stripped (lack of grease?) then I'd be pleased to know so I can avoid it in the future.
Regards,
