That was about all I got this weekend, but it was still progress.
Here you can see me checking that the ply will sit nicely across the battens, and if you look closely at the outside batten, you can see the end is tidied up, it's curved, tapered and clamped down to induce a suitable curve in it.
I have the last batten sanded on the inside - I won't bother sanding the the outside where it will be glued and screwed to the plywood until I have cut and fitted the ply and I'm ready to get sticky with it.
The battens are all now drilled and held in place by deck screws.
I did remember to unscrew all the blocking that becomes inacessible once the battens are in place.
The next patch of good weather should see me able to epoxy the battens in place, and as with the chines, I'll used deck screws to draw everything up tight and then replace them with bronze when the glue sets up.
Bronze screws are just too soft to try screwing 2" into Oak and pulling a bend into battens as well.
