One of the very last things to go on the boat is the metal rub-rail which wraps over the breast hook and along the stems onto the keel stringer. When you bend the piece in a vise, you can't quite get a sharp 90 degree angle, so what we do is round the top of the stem and gunwale to match the curve we do get. Do this now, before you oil the frame and other parts. Use the metal part as a guide, and sand by hand to get as close as you can to the required radius, but don't beat yourself up too much if its not perfect. As long as the arms of the metal piece lay flat on the stem and breast hook, it will be fine.
The installment of this piece will be covered later; for now, I just want you to have shaped the ends before oiling.
Note: when you do this shaping, you can save time later by putting the wooden rub rails on while you do the shaping, so they will match the profile of the bow and stern. Also round them off nicely on the outside.
This is what you'll need to do if you forget to round the rubrails when you round over the bow and stern. It seasy enoughn to go back and mark themto match and round off the ends to match the boat. A little Waterlox touch -up with a small brush will be required.
