Doodles...
Try it again?
this one is a 76 sq. ft wing which is not the exact right wing
for this plane, but the worksheet was already done-so...what.
No idea how the columns will hold up on the net, but .....
it's worth a try...
The spar caps are 1-1/5" X 1/8" 6061 with 1-1/2" x 1/8"
6061 straps layered to the indicated (interpreted) thickness.
Bruce bolted his spar, which produced a very straight spar
assembly.
Hammering big rivets into small structures will invariably
induce some distortion.
We are doing is a beam spar rather than a proper box, so the
sheer web dimension should be doubled.
And?
No promise that any of this is close to correct...

it.
