The boat will be getting a pre-preg carbon laminated fin with douglas fir shear web. It is important for the keel fin to fit accurately into the keel box. Gabe Murphy made a one-off tool for the keel fin using a CNC milling machine. The keel fin will be laminated in this tool. The tool has a left and a right side. Here are the two blanks on the milling machine table.
Almost done.
The two halves have been milled and are now sealed. The near end is the top and will form a taper to fit tightly in the keel box. The bottom has a tab that fits into a socket in the lead keel bulb.
All finished and ready for the lay up.
