The Percassa was fitted with one 40mm bofors gun and a smaller gun on the transom, I wanted to fit two 40mm bofors guns so i did a search on the net and came up with HMS Brave Borderer which was a variant of the Percassa and she had two bofor guns and also the cabin at the front of the bridge had been removed, which suited me,
I cut off the cabin at the front and also cut away some of the frame work, I cut and glued a new deck to the top back of the bridge and added some 1/4 round to the top edge for supporting the outer covering which is a very thin plywood, I also added sides of a thicker plywood, not shown in the pic,
To glue the thin plywood skin I first glued it across the top of the superstructure and let it dry overnight with a heavy weight on it, ( 4 inch vise )
next day after removing the vise, the plywood skin has to be folded down the sides and glued in place, I was lucky that I was able to remove all the glue that was on the thin plywood,
another view from the side, and you can see where I have cut the front of the cabin off the superstructure,
I folded the plywood down over the sides and glued it in place with the help of some wood strips and a few brass nails which I removed after the glue was dry,
best regards John,
