$3150 or best offer.

The Shenwai 12x36 engine lathe (specifically SW-900 model) is a Taiwanese-made precision machine tool regarded by many machinists as a higher-quality alternative to typical entry-level imports.

12-inch swing lathes are typically compact machines designed for light metalworking, featuring variable speed controls, robust motor, and a 12-inch swing over the bed to accommodate larger diameter workpieces.

Key Specifications

· The Shenwai 12x36 features the following capabilities:

· Swing over Bed: 12 inches (often up to 17 inches in the gap).

· Distance Between Centers: 36 inches.

· Spindle Bore: Approximately 1 7/16" (36mm to 40mm).

· Spindle Speeds: ranges from 60 to 1050 RPM (some variants reach 1450 RPM).

· Threading: Capable of cutting both S.A.E. (Inch) and Metric threads.

· Motor: Often equipped with a 2 HP motor, 220V single-phase configurations.

· Standard Tooling: come with a 3-jaw and 4-jaw chuck, faceplate, steady rest, and follow rest.

Key Aspects of Shenwai Lathes

• Model SW-900 A very common model, often identified as a 12" x 36" (12" swing over bed, 36" between centers) gap-bed lathe.
• Structure: They often feature heavy, cast-iron construction with hardened and ground bedways.
• Capacity: Many models have a removable gap, allowing for larger diameter work (often 17" or more) near the chuck.
• Drive Systems: While many are geared head, some older, 1970s-80s models use a V-belt drive with an open back gear.

Common Uses and User Feedback

• Versatility: Used in small machine shops, maintenance departments, and for school training.
• Replacement Parts: While specialized Shenwai parts might be rare, many 12x36 Taiwan-made lathes of that era share common components with Enco, Grizzly, or Jet, often making parts findable.
