He said "Join and reinforce intersecting Members"...

Close to correct application of parts! Anywhere there is two metal parts connect on a 90 degree angle, there is a "gusset" placed for reinforcement! While I never counted them, looking at the blue prints for a "B" model ponie, it has 12 ribs, which there are 4 gusset's attached to each rib where it joins the main spar, 2 in front of spar and 2 in rear of spar, for total of 48. The rear spar only had gussets at the front of the spar, 24, for a total of 72. I should have specified spar gusset ts only, as there are also many other smaller gusset's placed in various places in the wing for strenghting.
