What would a competent machine shop charge to do this? Most of us don't have a fully outfitted machine shop :-).

Bolt the two clamp sections to a lathe faceplate and bore them to the mast diameter.  Remove enough material to enlarge the contact area and insure the bore is true to the bases.  Use grade 8 bolts and use a torque wrench to max spec torque for the size bolt.  Repeat this tightening 3 times.

The clamp bore as cast wasn't straight to the machined base and only a few "points" would have made contact in the 2800 I have turning a 375# 100ft tip to tip 2L 80m beam.  Now it doesn't slip.
