Another update for the build.

I decided to mount the transom to the build frame on two vertical 2x4's that lock in to the corner between the floor member and back board of the transom. I was able to clamp the 2x4's to the transom, position the transom at the angle I wanted, and then fastened the 2x4's to the build frame.

I've also made progress marking out a centreline on the build frame to help locate the frames, and the stem. A combination of lasers and plumb-lines helped to ensure that everything was correct.

Another week, and a little bit more progress.

Encapsulating the frames has been much more time consuming than I had thought, but most of that work is done and I have moved onto cutting and. fitting the keel. I've got the keel in position and I think I've achieved the correct curve between frame #1 and frame #2, and a nice flat profile back from frame #1 to the transom.

It seems to take a lot of force to clamp and bend the keel into the notch in the stem and I think this will be a challenging joint to glue, clamp, and bolt together. I'm also worried that counterboring the heads of the carriage bolts too deeply into the keel will reduce the strength of the wood and may cause the keel to split.

Question for the community, how much material can I expect to fair off the keel in this location? how shallow can I afford to make the counterbores for the carriage bolts?
