End Taper Angle Sherline Mill Leadscrew
I'm converting an old Sherline mill to CNC. Seems this example is old and does not have the three piece leadscrews like more modern versions. My lead screws are all one-piece. I'm using Sherline couplers so this needs to be tapered.
Do any of you folks know the angle? Or can somebody perhaps measure a spare rod on-hand? I can machine the taper and threads on the end. Just need the specs.
It's the end of the leadscrew as shown in this image circled in blue:
Thank you.
