1.11 mm thick steel faceplate provides heavy, rigid support for turning and facing operations. The solid steel construction helps minimize deflection and maintain accuracy during use. Thread options (optional): 1 in x 8 TPI M33 x 3.5 M18 x 2.5 Back spigot design: Flat spots machined on the back spigot for easy removal from the lathe, simplifying setup and cleanup after use. Locking feature: Locking set screw for use on reversing lathes, helping secure the faceplate when lathe direction is changed. Key benefits: Robust steel construction for durability and reliable performance under load. Multiple compatible thread sizes to fit a range of lathes and spindles. Flatspigot back design facilitates quick removal from the spindle. Locking set screw enables use on reversing lathes, enhancing stability and safety. Applications and use scenarios: General turning and facing on lathes with one of the compatible thread sizes (1 in x 8 TPI, M33 x 3.5, or M18 x 2.5), for metal or wood workpieces requiring a stable mounting platform. Reversing lathe operations where the locking set screw is needed to maintain engagement and prevent slippage during direction changes. Projects that require frequent removal and reinstallation of the faceplate, where the back spigot flat spots speed removal and reduce effort. Compatibility and performance notes: Thread sizes provide versatility for compatibility with lathes that use 1 in x 8 TPI, M33 x 3.5, or M18 x 2.5 threads. 1.11 mm thickness offers a balance of rigidity and weight for stable machining. Steel construction ensures longterm durability for repetitive turning tasks.
