Marked, punched and drilled the holes for the pins, plus three glue holes to help bind the scales.
Alternate with semi circles. That is, every 20mm down one side and offset them down the other side. No reason for starting one side first. It just kind of happened.
I did these semi circles with the small 1/2" drum sander on the drill press.
Then added the "leafs" with a needle file. Looks okay for a first attempt. I'll have a go tomorrow at cleaning up the curves a little.
This now needs a clean up and I'll send it off for heat treating.
