On 11/2/12, I described why I did not like using scarf joints in an entry titled “No Scarfs Please”. The thing about scarf joints, though, is that they are really strong AND look really smooth.
The Mayfly plans allow the use of simpler butt joints, where two pieces of wood are laid side-by-side and joined using a backing plate. On a curved surface (in this case, a highly rockered bottom), they can be less than smooth, and the aft joint has turned out to be such an example. Note the raised edge at right and the gap between the plywood bottom and the underlying chine log. I’ll fill the gap with epoxy. But the raised edge . . . should I plane it smooth? . . . Fill it and fair it? . . . Leave it alone? Thoughts?
Note the penny on edge for scale . . .
