I love fixing sewing machines. I love seeing harrassed or broken machines being broiught back to life, cleaned and oiled and purring away happily. Unless your machine is a cheap plastic thing most machines an be coaxed back to life even after being ignored for years and years and the really old ones are utterly indestructible.
Here’s just a few of the horrors I’ve come across…
Keep your machine covered up and clean, change your needle often, use decent thread and the right bobbins, and don’t stitch over pins, and you should have a 
long relationship with your machine! IUf it does all go pear shaped come and see the doctor and I will fix her right up.
