Shopsmith Cast Iron Lathe Faceplates provide secure, smooth-running support for turning large or small diameter bowls and similar objects. Our 3-3/4 Inch Face Plate attaches quickly to any MARK model spindle with a single setscrew. The 3-3/4” diameter face plate is the ideal choice for turning small bowls, vases, and other objects that are larger in diameter than what you would comfortably turn on our Lathe Screw Center (505601). The inner set of three 1/4” diameter mounting holes can be used to grip workpieces as small as 2-3/8” in diameter while the outer set will grip workpieces down to 3-1/4” in diameter.
