Sewing Machine Repair
Laura's Blog: Do it yourself serger repair - How to adjust serger timing. So I think there is some kind of conspiracy going on. Considering that the local repair shops charge $100, it becomes very pricy to get your machine(s) serviced every year as recommended. Especially if you have machines that only cost around $100-$200. Maybe the sewing machine manufacturers are trying to keep the relevant information secret so you feel compelled to buy a new machine when yours breaks. I don't know.
