Hello Everyone,
I'm doing some repairs on my rudder and I am unsure about what I've encountered. There were 3 small cracks about 1 1/2 to 2" long with delamination around them, so I decided to cut into them and discovered water logged wood blocks behind. They were about 1/2" x 2" x 2" and possibly teakwood(nope, it's 5/8" end grain balsa). I dugged everything out and all seems quite sound including the rest of the rudder.
I'm wondering why they are actually there and how did it get that way. I know the rudder is built compartmentalized but those 3 spots seem odd to me.
I've uploaded pictures and hope someone here can elaborate on this.
Thanks.
