There are a few proprietary needle configurations out there and industrial machines often require different needles than domestic machines.
Why do you put the word expert in quotes? That usually implies the term is not applicable to the situation. If the person is not really an expert then maybe you should seek out folks who are. Like your local sewing machine repair shop.
He's the owner and repairman for the shop so I guess expert is correct...I guess it just seemed strange to call him that.
The issues with the needles were supposedly caused by the dog feet (slipping, catching, timing...i don't know).
