Next Phase ! plaster time ahead.
as you can see the silicone is rather lumpy, this is because I re-used
small shreds of old cured RTV in the middle layers. Because of
this, I think I can leave the registration bumps out of it.
I must confess 2 cockups :
*always* plan before you drill a hole
*always* plan before you saw a hole in a plank. The little built-up
of the boat is now crammed into a cut-out recess in the planking.
Otherwise the plank could not be attached full-length to the board..
My late grandfather would have been disappointed. He teached me
woodworking far better than this...
