SMITHY MI-1337L MANUAL LATHE

Technical Description

The Smithy MI-1337L Manual Lathe is a robust benchtop engine lathe designed for precision metalworking and general machining tasks. It features a 12.75-inch swing over the bed and a 37-inch distance between centers, providing ample capacity for a wide range of turning projects. The lathe is equipped with a 1.5-inch spindle bore, allowing for the passage of larger stock or the use of specialized tooling. Powered by a 1.5 HP motor (not 2.0 HP as sometimes listed), the machine operates on either 110V or 220V, making it adaptable to various shop environments. The spindle speed is mechanically controlled, offering nine selectable speeds ranging from 64 to 1500 RPM, enabling optimal performance for both light and heavy cutting operations. The lathe includes a feed screw with an 8 TPI pitch, supporting both longitudinal and cross feeds with adjustable rates for precise control. It is capable of cutting up to 40 different inch threads (from 4 to 56 TPI) and 26 metric threads (from 0.025 to 7.5 mm), making it versatile for both imperial and metric threading needs. The tool post accommodates standard 1/2-inch or 5/8-inch tool bits. The machine’s heavy castings ensure stability and vibration damping during operation, contributing to consistent accuracy and surface finish. The MI-1337L is suitable for hobbyists, small shops, and educational settings, offering a balance of power, precision, and ease of use in a compact benchtop design.
