MAIN SPAR AND OUTBOARD SPAR PRE ASSEMBLY

NOTE: IF THE SPAR SUB ASSEMBLIES HAVE NOT BEEN PREVIOUSLY PREPARED AT THIS TIME, REFERENCE THE WING ASSEMBLY SECTION AND COMPLETE THE REQUIRED SPAR SUB ASSEMBLY.

 


REAR SPAR

The rear spar is fabricated from a strip cut from the same 1/4 inch aircraft plywood as used for the firewall.

 


MAIN SPAR LOCATION AND INSTALLATION

POSITIONING

The position of the main and rear spar cut outs is located either by using the spar locating jig shown in the attached figures, or by laying out lines in the fuselage using the dimensions shown in figure XXX. The spar locating jig method has been used with good results by the builders of the two place KIS. Kits later than serial no. 7 have the critical layout lines scribed in the mold which transfers to the outside of the fuselage, and most of the following steps may be ignored..

If you intend to use the jig, fabricate it from materials with good dimensional stability such as plywood or high density fiberboard.

 


SPAR MOUNTING LAMINATIONS

Once you are satisfied with positioning, you can install the inner wet "pre-lams" to the spar.

For the main spar, prepare the BID wet lay-ups on plastic sheet as described in the procedures chapter ( Pre lam's).

-one, 8 by 12 inches,

-one, 6 by 10 inches,

-two more for the sides 6 by 10 inches each.

This should result in a minimum 8 plies across the top, and 4 plies along each side, and at least 12 plies in the overlap areas of the top comers (much stronger than required). Allow all these inner lay-ups to cure before removing any clamping or fixturing. See figure XXX

Follow the same basic procedure for the rear spar, using either the jig, or the dimensional layout procedure. Also clamp and use elastic straps to position the spar, and check dimensional integrity and square and level from as many reference points as practical. Shim if required, and tape the outer fuselage so you can apply the dry FLOX fillets.
