Scarf joining the Chines

So the boat is 16' long which is a very hard length to find in lumber. To make the Chines I am trying to join 2 pieces of mahogany which are about 10' long each.

Turns out scarf joints are a lot harder to get the hang of than I thought they would be. I made a few failed attempts but this time it is looking promising.

The 2 Chines are currently clamped and waiting for the epoxy to harden. I wrapped the joints in parchment paper and then clamped them with scrap pieces of plywood, For some reason the epoxy seems to let the parchment paper just peel right off, and if it doesnt its a lot easier to sand some paper than it is to break apart 2 pieces of wood that have epoxy on them (learned the hard way).
