Wing tube advice
#26

First of all, center the holes for the wing tube between the spars. This will leave 1/8" of the wing tube in front and in back of the spars. There are two ways to sheer web from the tube to the spars. The most common is to cut small pieces of sheer web material to fit between the top of the wing tube and the center of the underside of the top spar. Do the same for the bottom . The other method is to cut 2 top and 2 bottom sheer web pieces for each rib bay. For the top 2, the bottom of each piece will be sanded to an angle to match the contact point of the wing tube, and the top portion will be glued to the front and back edges of the wing spar. Either method will work, if you choose to use the 2 web, front and rear method, use thinner / lighter material for the webs as there are two of them.

GENIOUS!!
It's been so long since I've built a plane. I haven't flown in 6yrs and I'm rusty on everything. Your comment joggled my frog brain and I remember now. You are exactly correct in how to shear web it when sandwiched between the spars.
THANK YOU SO MUCH!!
