Thanks Ken! I used black starboard. 1" thick. 12"x12" pieces are available from McMaster-Carr for about $35. Knowing that ultimately my starting size would need to be roughly 5"x5"x2", I decided that a 12"x12"x1" piece was going to be the smallest usable and available size.
https://www.mcmaster.com/#9785T412 I started by cutting 5 pieces 6"x2" and stacked then together for a total of 5x6x2. I clamped them, applied masking tape, and traced the chock. For ease of managing them in the saw I cut the tape so that each layer could be separated. Used the saw to cut each piece a bit proud of the trace. I then reassembled (re-stacked) and finished the sides on the drum sander. I now had a 2" thick block that followed the footprint of the chock. I carefully marked centerline before separating each layer again. This time I masked each layer on it's "inside" face - the face which originally measured 6"x2". On this face I carefully measured and traced the template of the curvature of the mast on to the tape. I then returned to the bandsaw and cutout the curvature of the mast, again proud of the template. Now back to the sander. I started with the largest piece and was careful to regularly check the fit to my template. Once I had the first one done, each of the successive pieces was checked to the template and to its neighbors so that a smooth and even fit was accomplished. A feather edge of flashing was left after all of this sanding so I re-clamped and assembled the pieces and used the sander to dress everything up.
