I am about to leather my oars and have a question from the brain trust on button placement. I know some place them as stops and they ride against the locks. They can also be placed closer to the oar handles and are just to keep the oarlock from falling off the oar. I don't expect to be rowing Lula much, just to get me home when the wind dies. If I were a more experienced rower and intended to be rowing Lula for long periods I think it would make sense to have the buttons purely to keep the oarlocks in place and not rubbing on the locks. In my case, maybe not. Any thoughts or advice appreciated.
