What you exchanged for is actually a component for an upgraded part. That prototype locked behind the lumber takes the item you traded for along with other materials to create an upgraded part you can actually use. The lumber comes from submersible ventures in the newer areas. As DrWho2010 said, you'll want to check out the submersible thread. The first page of posts has some good resources and then you might want to hit the end of the thread and work your way backwards little by little.
