I'm working on a 1913 OT Charles River CS and have cut new pieces for the tops of the stems that are now expoxied in place with no other fastener. I've seen a number of techniques for securing the stems to the inwales and deck, and also reinforcing the connection between the old and new stem components. In weighing all the different approaches, it occurs to me that I don't really know what I'm protecting against. Here are my questions: 1. When stem repairs break in use, where or how do they normally break? Am I correct to assume that the weak point is the connection between the old and new pieces of the stem, rather than the connection to the inwales and deck? 2. If I try to reinforce the connection between the new and old stems with a screw from the back of the new piece going into the back of the old, won't I be weakening the old stem by removing more wood?
