Steve, what Rich is saying is that the cabin roofs on big D were not domed but had a gentle arch as Dumas made it. What dumas did not have you do was put a smooth curve transition from the top to the sides. See photo of big D and mine done as Dumasplans with the arched roof but no curve at the joints. Rich is saying you just need to round off those joints rather than build the roofs higher by adding material on top of them.

Hi captains,
Sorry that I have not been participating too much on the forum. Recently I started a new job and the training has been very intense...I don't have the luxury that I had at my old job where I could post at will.. I have been using my cell phone to chime in and it's very sporadic. Hopefully when we relocate life will settle a bit more.
Bill basically said it all in his post and my little comments basically reinforced his point.
The Dumas wood is 1/8" thick. When you take into account the thickness of the side wall and the thickness of the roofline you have enough to work with to 'erase' the sharp corners on the cabin sides. For the windshield more shaping needs to be done. So, per my comment above reinforce the inside seam with epoxy and sand the windshield to the roof in such a way that it slopes back and looks natural. Once the windshield is shaped put a layer of epoxy on the outside so that the finish will look nice.
For the trim, it should be placed 1/8" below the roof and for the windshield it gets more complicated.Try to keep it as straight as possible and try to avoid letting the trim ride up with the roofline.Here are pictures of my superstructure during various stages of shaping..This should be a good reference point to guide you.
