I spent a lot of time thinking about the measurements for the keel, but nothing really prepared me for the first rough cuts.
These are going to be the keel.
After I cut out the seven transom pieces I sanded them all to the correct thickness with Byrne's thickness sander. Then, overnight and while wet, I put them all in this jig to give them a slight downward curve. I decided to bend them instead of sanding them to save pear wood.
