This 8 1/2" diameter face plate can be fitted to lathes with spindle threads from 1 1/2" to 2 1/4" diameter. The FACE PLATE (S-5879) has a deep rim which allows it to lie flat on the workbench to aid in setting up workpieces (note: some lathes may not permit mounting with a full depth rim, in which case the rim may have to be trimmed back). The casting for making the FACE PLATE (S-5879) is stress relieved cast iron with cored "T" slots. The FACE PLATE (S-5879) can be machined on the lathe except for finish machining the "T" slots which requires a milling machine. Besides the casting, the kit for making the FACE PLATE (S-5879) includes drawings and machining instructions. A drawing is included showing how to make a centering accessory (at right in the photo).
