INSTALLING THE FUSELAGE STIFFENERS
..... Two stiffeners, fabricated from the 3/8" thick white foam, are placed on each side of the fuselage above the canard. These stiffeners improve the stability of the fuselage sides during hard landings. The sketches show the positioning of the stiffeners. Two BID are laminated over each stiffener to attach it to the fuselage and canard. PERMANENT ATTACHMENT OF THE FORWARD AND AFT FUSELAGE SHELL
..... If you have decided not to make your Q2 trailerable, you should now complete the closeout of the fuselage by permanently attaching the forward and aft fuselage shells at the fuselage cut line, or joint. .....If, on the other hand, you intend for your Q2 to be trailerable, you should skip ahead in these plans to Chapter 15 and complete that work prior to mounting the vertical fin in Chapter 14. .....The fuselage shells are permanently attached at the joint with flox and BID tapes on both the outside and inside. Begin by jigging the two shells together and checking for fit at the joint. .....Then, since the core thickness of the forward shell is 3/8" and the rear shell core is only 1/411 thi ck, bevel the forward shell to match the aft core at the joint. Also, sand dull the inside skin glass within 2.5" of either side of the joint, in preparation for the inside joint lamination later. Prepare some scrap lumber for use in holding the jigged position. Mix up flox and spread it on both edges of the shells where they will join. Place the two shells together, hold them in position with the lumber and Bondo, and permit to cure. .....Next, laminate the 3 BID tapes shown on the out¬side of the skin after you have sanded dull the exist¬ing glass. Note that the three tapes have the following widths: 5",4", and 3" and that the orientation should be at 45 degrees to the joint itself. Wherever it is necessary to overlap BID in order to laminate around the entire circumfey'nce, overlap the BID by a minimum of 1.5". .....Once that lamination has cured, craw1 inside the fuselage and perform the inside skin lamination as shown, wherever possible. The 4 BID tapes have the following widths: 5",4",3", and 2" with a 45 degree orientation to the joint. The extra BID is to make up for the glass strength lost when the foam was bevelled. |
