I have done a lot more but too long to explain in details. But basically the 29" of longeron twisting to fit the engine mount brackets was not easy to do.
Other errands I did were to triple check squareness, position and alignment as this needs to be as straight as possible to have a staight fuselage where all the mating parst will fit all together. It is not the time to make a mistake so I have been taken the time to insure as close as possible to perfection.
