![]() 1494 forum posts 403 photos | It's been lurking under my bench for years but curiosity has got the better of me. It's a shop made aluminium face plate 195mm diameter that would fit a lathe spindle with a 1.5" x 6 TPI thread. So what lathe/s would that be? Rik |

Could be for a Harrison graduate wood turning lathe Yes, indeed. Harrisons offered 355 mm dia aluminium "faceplates" with left hand thread which were actually sanding discs for the outboard sanding attachment. |

Just to clarify - this faceplate has a right hand thread. Rik By way of further clarification, both left and right hand threads on the Graduate also have a short plain register ie not threaded to shoulder. This arrangement has the interesting advantage that chucks can be made to fit both ends of the spindle by machining both left and right hand threads in the same backplate. |
