When the micro has cured, rotate the table 90 deg nose down so that the shear web can be done.
The shear web extends from BL52 left to BL52 right.
Note that the glass wraps around both the top and the bottom of the wing, so that the shear web corner will have to be rounded slightly to get the glass to lay down. Also, at L52, the layup turns 90 deB, and follows to the trailing edge of the wing, still wrapping up over the top and bottom surface(which, therefore must be ‘scooped’ out .026” so that the two plies will fit flush with the rest of the core.
After laying up the two BID at 45 deg. for the shear web, the rear half of the 18-A-B-C-18 hot-wired piece can be reattached with micro. Use tape to hold the combination together until it cures.
TRIMMING THE FOAM CORE
At this point, the wing should be jigged on your layout table upside down. Using a hard block on the foam core) clean up all joggles, excess micro, and bumps. At BLOO, round that joint so that the glass can flow smoothly across BLOO.
Read over the section on “Mounting the Main wing” to understand how the wing fits on the fuselage.
The shear web that you previously laid u fits against the forward face of the FS89 bulkhead. Measure the width of the fuselage at that point and mark it on the wing foam core with a pen. Mark BL9.3 on each side at the trailing edge of the foam cores and connect up the BL marks. before cutting out this section of the foam core, measure the fuselage to verity that after the cutting, the foam core will project inside the fuselage to the aft of the FS89 bulkhead. If not, change the BL9.3 mark so that the core will project inside the fuselage in that area.
Next, you need to cut off the “nose” of the main wing so that it will fit against the seatback bulkhead. Measure the distance from FS89 bulkhead to the seatback bulkhead on each side of the fuselage, and place marks on the foam at the corresponding locations. Connect the points spanwise with a pen. Tq
