Hi all. Working on my CH18 kit and building with flush hatches. I've cut out the forward hatch and originally planned to use the formers included in the kit to get the curvature of the deck. But looking at the sawed out hatch, there is a fair amount of twist. I don't think the formers, by themselves are going to take that out, but I might be wrong. Plan B is to go with the recommendation in the "tips for boatbuilders" and laminate another piece of 4 mm over a mould. Looking at the supplied hatches with the kit, both have about the same amount of twist. In fact, the piece I cut out of the doubler I am gluing to the underside of the deck has about the same amount of twist as well. My inclination is to go with the laminated 4 mm approach and flip the pieces so the twist cancels itself out (hopefully). Any suggestions much appreciated!
