Hi again Bob.
I did not really mean to comment your foam jig system, it was more to those who use more classical wing jigs.
Another thing; if someone wants to optimize, the cap strips should have a stronger joint with l.e. sheeting than the butt-joint that everybody use. The strips should be recessed into the sheeting so that it has a good shear joint with main spar. Only then the caps can take all the loads they are capable of taking. I guess many of us have noticed how the wing stiffens when tip blocks are glued on. That just indicates that the ribs don't do their job properly.
Of course, our wings are so thick and weight/material volume is not such an issue. In free flight it is a big issue, if just one of about 100 ribs crack, the model becomes unflyable.
