I don’t own a duplicating lathe. So when I needed to turn several identical spindles, I designed the fixture shown in the sketch above. It was convenient to use and saved me a lot of time.

To make the fixture, first cut a negative profile of the spindle shape from 1/4-in. hardboard. Divide the profile into convenient sections, and attach the sections with hinges to a support piece behind the lathe bed, level with the turning axis of the lathe.

Prop up the sections in the open position out of the way and turn the spindle to rough dimensions. Use a simple gauge as shown to size the major diameters it’s faster than using adjustable calipers.

Continue to turn the spindle, approximating the shape by eye. When you get close, flip down a template section in the area you are working so that it is riding on the turning spindle. Continue to remove material and refine the shape until the template drops into place. Repeat that process until all of the sections have been duplicated. With just a little care, you can hold tolerances to within 1/32 in. For final sanding of the workpiece, flip the templates sections up out of the way.
