I managed to achieve a pretty decent bend on the bulwarks - at least laterally. There is a very slight mismatch at the bow, where the hull continues to curve inwards, and my bulwarks to not quite follow the same curve. I’m not sure if there is a better way but a couple of attempts using my ‘nail on board’ method got me quite close. The dry fit of bulwarks and transom is below. The hull already had a slight ridge where the transom and bulwarks would sit, but I found that I had to sand away a little extra to ensure a flush fit:
Contructo recommend using glue and nails to attach both transom and bulwarks. I’m trying to avoid using nails wherever possible.
The transom went on first. To try to get the correct angle flush with the stern of the hull, I raided my son’s Lego box and built a quick guide. Coupled with the dry-fit bulwarks the result looks OK. I painted before fitting to avoid mistakes as the margin for error between transom and hull is very small.
Finally I painted the bulwarks and glued them on. I could not find any way of clamping them, so ended up glueing bit by bit from bow to stern, and holding them in place whilst the glue set. At the stern, the bulwarks lift slightly. I’m not sure if that was a result of my bending. However, the gap is small enough that it will be covered by the wales when they go on. I will need to fill slightly so that the gap is not visible when looking directly at the stern. A quick note on colour - I wanted to match the reddish brown of the box art for the bulwarks. The included (and subsequently binned) paint was a brighter red. Handily, Revell do a matt acrylic paint called ‘Reddish Brown’ which I think looks quite smart.
