Looks like you're on the right track Bill. If it's any consolation to you, after building my B-24, I don't believe that they have to be perfectly aligned. I got real close on the Herk, with the method I used, but I know it wasn't perfect. But it flies great.
The B-24 was another story. I had one dickens of a time getting those nacelles aligned because of the offset between #1 & 4, and 2 & 3. Even had to take one off and do it over it was so far out. It wasn't as easy to get the alignment as it was on the Herk. Anyway, there is definitely differences in the alignment on them. I was ready for some major trim problems on the first flight, but it just didn't happen. On a twin, I think it would possibly be magnified. But so far, I've got two four engine planes that you couldn't want to fly any better than they do. This bird you're building is a sweetheart. You'l love it. I'm going to fly at another site Sunday, out of a field that is much shorter than ours. Might be time for some STOL practice!!
