Thnk you Jim
Somehow Fast-Food-Tinkering does not work for me somehow.
I already started planking the outside with poly but could not find a pattern for the width of the planks - Frustration taking over ...
Then I realised that as I cutted the ports "free hand - first sight" was the problem, as the planks are following - unlike the 1765 original planking -
exactely the row of the ports. So considered a second (or even more look) to get things straight and realised taht all planks have more or less same width. So I took the illustrtion programm and started to push the measures until it fitted the photographs and suddenly it all worked out. 21 cm planks it was what I needed and some correction on the ports.
Also Business as usual - removing the first trial of planks
New planks were cut ...
... ports newly defined ...
... cleared with plenty of blood, sweat and tears ...
.... and cut free.
Just see on the inside of the ports the difference to the first fit :-O
Fixed the first goodies, soon more about that
And here we go, twice the same section of hull, just a bit more than 100 years of difference.
