Shopsmith Cast Iron Lathe Faceplates provide secure, smooth-running support for turning large or small diameter bowls and similar objects. Our 6 Inch Cast Iron Lathe Face Plate attaches quickly to the spindle of any MARK model with a single setscrew. The 6” diameter diameter face plate is recommended for large diameter bowls, platters, trays, plant stand tops, and similar projects. This faceplate arrives dynamically balanced for vibration-free performance. The inner set of three 1/4” diameter mounting holes can be used to grip workpieces down to 2-3/8” in diameter the middle set down to 4” in diameter and the outer set down to 5-1/2” in diameter. Each set of holes is off-set slightly so that if you need to remove the turning block from the faceplate, it only goes back on the faceplate one way.
