This is a machine dedicated to straight stitch only, built for quilting and heavy fabrics: the frame is cast aluminum with eight ball bearings, and the hook is a vertical, full-rotary industrial type, with a bobbin holding 1.4 times more thread than a standard one. It sews up to 1,600 stitches per minute.
Stitch length reaches 6 mm, presser foot pressure is set with a graduated dial up to 11 lbs, and the extra-high foot lift lets more layers through than its size suggests. The thread cutter is automatic, the needle threader is built in, and the knee lift frees both hands on the work. Thread tension stays manual, for finer control across different thread weights. The bobbin winder has its own motor, so it doesn't interrupt sewing while winding.
This is pure straight stitch: no zigzag, buttonholes or decorative stitches, and no free arm for tubular work. It suits someone assembling or quilting substantial projects continuously and wanting a fast, precise straight seam, not someone looking for a second machine for everyday jobs.

Pros and cons
In favour
- It sews up to 1,600 stitches per minute, well beyond a general-purpose domestic machine.
- The bobbin winder has its own motor: winding does not interrupt the seam in progress.
- The knee lift for the presser foot leaves both hands free on the fabric.
- The cast aluminum frame holds up to continuous use better than a plastic body.
Worth knowing
- It sews only straight stitch: no zigzag, buttonholes or decorative stitches.
- Thread tension is set by hand, with no automatic system to set it on its own.
