Here you can see the extra width at the shoulder. I have the first side almost done and just need to make more templates to be sure the two sides end up being the same.
The other side with the template in place where all the fill needs to go. I have left the shell open just in case I need to add some material on the inside. I did need to cut some away and fill in the nose to get a nice shape as just cutting the original apart and rejoining it longer caused a bump to show up. The orange bit is the modification to add the rain gutter to the mould.
