Plastic pipe makes good insert for reverse chucking of small items.
Choose the size of plastic pipe that will fit (or is close).
Cut a slit down the side (or take out a section) so the plastic pipe or tubing fits around the turning. Slide both into the chuck jaws and clamp down.
The plastic protects the surface while transferring the clamping force onto the turning.
Diffferent kinds of pipe will work. For instance, plastic electrical conduit, PVC pipe, water feed tubes, etc. In the following photos, 1¼" plumbing drain pipe was used.
Photo 1 = Top of turning completed, the slit tube sitting on the lathe ways.
Photo 2 = The turning reverse chucked in the chuck jaws and insert.
Photo 3 = At speed, the insert is visible within the shadow of the spinning jaws.
Photo 4 = Completed turning with insert still in chuck jaws.
