Hello Remondo,first up, thanks for the mail! It seems a long time now since I did the stern part, what I did was,(I think!!) the rearmost top part was cut into quarters so I could 'jiggle it' to fit the width and length of the revised stern once it was fixed. It was sort of repaired with bits off the frets, but I wasn't out to make a perfect repair as this was going to be covered at a later time with the printed deck part anyway.
If you look at the 'real' Bismarck you'll see that even the new resin part still has the anchor wrong, it is much closer to the deck and the bottom of it is nearly touching the last of top portholes. To fix that, the 'spacer' that you are supposed to fit under the rearmost deck part, well, I personally disguarded that. (even with such a drastic change the aft resin part still fitted the shape of the stern pretty good and I had very little filling to do on its bottom and sides to get the thing flush with the planking!!)
Having still retained the old stern part, I carefully cut out the whole anchor pocket (it resembled a miniature swimming pool!!) When the aft portholes were eventually all in their correct position, I marked out the position of the 'new' anchor pocket in relation to that top last porthole and it's position to the deck, as per the photo I had of the 'real McCoy' When I was satisfied that I had it right, I drilled and shaped out the new hole for the 'swimming pool' Once that was superglued in position, it was filled with 'Tamiya' putty, sanded when dry and "walla!" , a new repositioned anchor pocket, just a bit better positioned than the Amati one, well I thought so!! If you look at the last lot of photo's I submitted , in the stern shot, you can see how much the anchor was moved by the white mark to the right of it!!
To sum up, it was a while ago and unfortunately I didn't take any photo's, it's not a job for the faint hearted to try!!, but in my mind it was well worth the effort, so why not?, it didn't cost me anything and it looks more correct!.....Dave.
