Try Model Expo. They sell wood. Also Micro Mark. And, take a look at the ads on the right side of the Home Page. Some of them may sell wood strips. It doesn't have to be limewood. You could probably substitute basswood. There is no "exposed" bare wood on the finished hull. Everything is painted. I can send photos of the finished hull if you would like to see the finished product, or any salient portion. I broke my upper left arm back in Dec 2018 so I know how it limits your motion....and hurts (I'm 79). Keep on truckin'.....
