I started this project in the summer of 2014, but really didn't get very far until the spring of 2016. Now I'm moving along well and wanted to share my progress, as well as ask questions from time to time. A couple of other Candlefish builds have been documented on this forum, and I continue to reference them.
I created the scarf joints using the step method and a planer. I tried a number of methods on scrap wood, and preferred this method.
I used a 2x4 on one side to keep the sheets of scarfed plywood aligned while I glued them.
