first time, the lead was covered with packing tape as mold release, and the stub slathered with thickened epoxy, the lowered into alignment. That gave a perfect fit of keel top to stub. Then picked up, cleaned off, and bedded in 5200.

When I see a big bulb on a narrow stub as shown in the photo I get very nervous. The keel bolts are very narrowly spread and highly stressed. They are not in a line so that the outermost are stressed even much higher. The leeward edge of the stub is going to receive tremendous compressive stresses. That isn't the sort of fin keel construction I would want to take into heavy weather out of helicopter rescue range....
