Additional Information:
Metal gear sewing machines save you from the most expensive gear jobs. Plastic gears can wear faster, loose their teeth and come out of time. Metal gears also hold up better when sewing with heavier fabrics. Metal gears may be a little noiser and require more lubrication, but make the machine last longer because of more resilient parts.
