Copper nails and roves, what size to use.???
I am building a 18ft launch, using copper nails and roves and lapstrake planking.
The boards are 1/2 inch thick.
It will have an inboard diesel 18 hp engine.
The board are 6 inches wide and there will 10 on each side.
The question is what size copper nail I should use and how far apart they should be spaced?
Where could I find this info.
Have several wooden boat building books that describe the technique, but no comments regarding sizes, etc.
