do a lot of "heavy" leather sewing with my Tippmann Boss and love it. However, I've had a lot of requests lately for products that we make like purses and handbags that the Boss can easily handle., but is a little slow at and doesn't have the reacht to sew deep inside (10-15") without a lot of material maneuvering. Any suggestions for a good machine that can handle leather weight (4-10 oz) sewing with easy material movement , deep reach and speed?
