Anastatia

I also just purchased a Singer 111w155. I need to get a servo motor and speed reducer. When looking around on Google, it’s confusing. I see some sold as packages or sets and some individual as well as several brands for each . Is one brand of Servo motor better than the other? What about the speed reducer? My plan is to sew leather briefcase’s and handbags. Thanks for all of your “ 2 Cents!”
