Thanks for the nice thoughts, Mark.
I instituted Plan B. I used the redrawn parts as patterns and cut new parts out of 0.040" styrene. The formers were the correct width now and reached to the corners of the top knot roof. I didn't cut the new base for it yet, but will do that on Monday. That said, when I went to skin it with 0.015" styrene, I was unhappy with the results. It doesn't sheet evenly, but distorts between the end and middle former. I may have to go with Plan C. I not sure yet what Plan C actually is, but I need to find a different sheeting material the will only bend in one axis. I may go back to thin balsa, but I'll have to buy some new fine-grained material at the LHS. Another possibility would be to use card stock, or individual planks (which is probably how the original building was constructed in 1870).
This pic has the assembly upside down. The square plastic base is on top and is not glued yet. You can see how the shapes reach the corners. I took care to ensure that the middle former is actually in line with the corners.
Here was the first piece of thin stock glued in place. To keep it tight to the curves, I took a 1" brass bar and pushed it against the sheeting and held it there with lots of rubber bands. You can see the distortion on the left lower edge. Plastic was held to ply with medium CA and accelerator.
When I tried it on the building, the width was correct. The height of the base is wrong, but I'll fix that with a new base.
Have a safe, dry weekend. If you're north of the Ohio Valley and in the Northeast, you're gonna get a nice reminder that there still is a Winter. We're supposed to get 2" here in the L'ville, but temps are going to drop fast and freeze everything quickly. It's when that sign, "Bridge freezes before road surface" is something to which you need to pay attention.
