Screw Cutting Attachment for Levin Watchmaker Lathe. Attachment is designed to mount on the end of Levin 8mm or 10mm Lathes with open Ball Bearing headstocks (‘open’ = pulley visible in middle of headstock). It is mounted on the end of the bed with two 10-32 screws. Will work with the Levin 12″ long WW bed or the older 18″ long Instrument lathe beds that have the 2 removeable pedestals (not the later beds where the pedestal and bed were one casting). 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. If your cross slide does not have that feature, you will have to’repivot’ the end of your leadscrew to add this extension. Set includes the Screw Cutting Attachment with 3 arms and gear mounting tooling, drive shaft, 60 tooth spindle drive gear for Ball 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. 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 base plate, arms, and gears are nickel plated and may have some tarnish or flaws in the plating. The free listing tool.
