Somewhere something went wrong here and had to be 'creative'. This is not what the model maker intended. Those familiar with the model will notice that the sides (particularly the back) is a lot thicker than the single plywood shape intended by the instructions. I had to pad it with balsa wood and then had to frame the inside of the windows with 0.6mm veneer to clean up. Also then used 1mm planking strips then on top of the balsa to plank the sterncastle (which was also not intended by the plans). All this because I cut the upper hull planks to short and at the wrong slope.
The sterncastle will be painted which is why I used wood filler here which really looks ugly on these pictures. It was (is?) worrying times - concerned that I messed up a reasonable model at this stage. Still some concern - but hope to be able to save the look - the window frames will be out of scale - but there will be many other items to focus on on the completed model
