How does the double-capacity bobbin work?
Gammill’s patented Automatic Thread Escapement system allows you to use the double-capacity “M” style bobbin. Since it releases all stress on the thread as it passes through the escapement, superior stitch quality is achieved regardless of speed. • How do I know which model best suits my needs? The throat space on each model determines capacity for piece size, batting thickness, and pattern width. Since Gammill offers four long-arm sizes and a short-arm model, there’s a Gammill machine to fit every need and budget. If you’re planning to machine quilt as a business, we would recommend either the Classic or Optimum size machine. The Classic’s 26″ by 10″ throat space is large enough to handle any quilt a client might ask you to do. The Optimum’s larger 30″ by 12″ throat would be better suited to the quilter who also does bedspreads (which are larger than quilts and use thicker batting), the quilter who prefers wider patterns and a larger work area, or the quilter who simply wants to roll
