I fell for it mate, I just followed the instructions in order, Doh!! It wasn't till i found these forums and realised it would be better to put all the cannons in place first. Schoolboy error i guess. I will have to make a long stick and somehow start aft and do them a row at a time, and somehow get them into the right opening and reach through from the opposite opening and put a drop of CA glue under the carriage wheels and let them sit on it., I have no choice cos there is no way I am cutting the upper decks off to get to the gun deck. Not happening., worst case scenario I do what I can reach from the opening amidships and close the gun port lids on the ones I cant reach.. We'll see, got to finish those pesky green tiles and outer planking first. Wish I had found YT before I got that far..
