Post diameter and construction - Post diameter: 5/8 inch hardened steel. Designed to resist loosening from vibration or impact, suitable for most mini and medium sized lathes. Unique design and usability - Curved design with a curved contact surface for secure use. Facilitates convenient and fast tool adjustments and supports a range of bowl and turning tasks. Sliding performance - Smooth sliding surface with no need for readjustment. The top of the post is a glossy hardened steel surface that allows easy movement of lathe turning tools. Material and durability - Forged from high-quality steel, offering high strength, rust resistance, and wear resistance. Built for long-term durability and high load bearing capacity. 2-3 practical use scenarios - Bowl turning on a mini or mid-sized lathe: curved rest provides stable tool support for shaping rims and interior curves with consistent control. - Spindle turning and hollow form work: enables quick tool height adjustments and smooth tool movement for efficient workflow. - Finishing and detail work: stable support reduces chatter, while easy tool sliding speeds up changing tools during detailed passes.
