Well I've finally got back to the Bugatti and to putting some louvres on the bonnet. I had intended to cut my own louvres because the Bugatti ones are square at the end rather than rounded, but making the louvre dies was turning into a never ending project, so I bought some standard louvres and cut them into two strips. The plan is to recess them into the lightply on the bonnet, epoxy them in and then use body filler to blend the edges. Because I'm cutting these from a square with two columns of louvres, the edges that I can use to attach the aluminium to the light ply is fairly narrow. "Clamping" them in place while the epoxy dries has been a bit of a challenge.
