RE: Ed's Ziroli B-25 Build
Now that the outer panels are framed up I started the process of fitting them to the center section. I set the center section back on the building board over the pans such that I can work on the entire assembly at once. For the wing tubes, I will use tube sleeves in the center section while the aluminum tubes themselves will be permanently epoxied in the outer panels.
For the first trial fit, the center section tube holes were a snug fit and the tubes exited the center section nice and level. So in order to adjust the droop of the outer panels, (1/4" at the wing tips) I enlarged the outer panel tube holes and cut snug fitting "donuts" that will be used to epoxy the tube in place once the wing panel is aligned perfectly. To get that 1/4' measurement, I placed my long piece of angle aluminum across the high points of the center section extending out to the wingtip. As you can see in the last picture, even with the tube holes in the outer panel enlarged, I am still nearly an inch off. So tomorrow I will take it back apart and open the holes up a little more to get the 1/4" measurement.
