Screw Cutting Attachment for Levin Watchmaker Lathe. Attachment is designed to mount on the end of Levin 8mm Cone Bearing Lathes with open headstocks (‘open’ = pulley visable in middle of headstock). It is mounted on the end of the bed with two 10-32 screws. Screw Cutting drive shaft is designed to attach to the end of the cross slide leadscrew that extends out the side on Levin, Derbyshire, Marshall and some other cross slides. You will have to’repivot’ your leadscrew to add this extension if your cross slide does not have that feature. Set includes the Screw Cutting Attachment with 3 arms and gear mounting tooling, drive shaft, NOS Levin 60 tooth spindle drive gear for 8mm Cone Bearing Headstocks, 11 change gears, pin wrench and a copy of Levin gear/thread tables. The pin wrench is used to help tighten or loosen the knurled nuts that hold the change gears in place. Change gear tooth counts are 36, 40, 44, 48, 50, 54, 60, 72, 84, 96, 100. This allows you to cut a large number of different threads. If your cross slide lead screw is metric the output of your screw cutting attachment will be threads per centimeter. If the cross slide has inch leadscrews the output of the attachment will be in threads per inch. 127 tooth translating gear (not included) allows you to cut metric and inch threads regardless of the type leadscrew in your cross slide without the translating gear, the attachment will cut the same style threads as your cross slide leadscrew….. If you have a metric cross slide, it will cut metric threads, if you have an inch style cross slide it will cut threads per inch. The screw cutting attachment does NOT include the lathe or cross slide, or cross slide tool post or cutting bit. On some Levin lathes the 2 holes in the end of the bed are not tapped and will need to be drilled deeper and tapped. The free listing tool.
