I am looking at a fuselage project that has the main wing attachment bolt holes already drilled in the fuselage bulkhead (that is under the pilots/passenger legs).

I have a set of wings that are completed. Is there a reasonable way I can mate these wings on this fuselage and account for the likely issue of the main wing attachment bolt holes not matching up perfectly?

I would remake the fuselage spar , Make a new spar and mate it to the wing, using the attach fittings, then install it in the fuselage. Duke and I just did one.

Thanks Bill. I just bought it.

well, here she is. Now I want to mate the empennage and wings, and go make airplane noises...

Looking good Billy Ray ! One thing you might want to do is remove the "red" tape , especially if it is the really sticky stucco type tape . If you leave it on too long a lot of the adhesive will remain on the AC when it comes time to remove the tape . Then its a lot of goo be gone (water based only !) to get the funky stuff off . Go ahead , ask me how I know . Go ahead ask me !!

Its the T variety.

Bruce : My knowledge of the "Red Tape" came to me in a vision while moving the controls behind the curtain ! Actually from using the stuff for many years around the house , especially when using it to put up plastic sheeting to protect the house when pouring concrete . It was the only stuff that would stick to the stucco siding of the house and then the name..."Stucco Tape" was born ! Yes , it is actually called stucco tape . The holding power was so good I used it for other projects and when I left it on too long...well you know the rest of the story . You can find it at Home Depot in isle 7 , bin #11 .

A note on drilling the spar bolts...I made an eight degree angle out of 1/4" x 2" angle iron overall length was about 3 feet. Clamped this to the spar and using a mill drilled the holes, repeat the other wing spar. This will give you the same dihederal both sides. It might be less or more than 8 but will be the same each side. I always say make the same mistake both sides and no one will ever noti

that's a good tip Bill, thanks.

Got her home and on the gear (tailwheel is temporary). Happy Turkey Legs!

Looks good looking forward to progress pictures of your project

Looks like the partially completed project I bought back in 1984 ! One tip when you get ready to make the trim strips for the canopy and windshield , go to the 99 cent store and buy a bunch of the large poster boards (2 for 1.00) and use then to make your templates before you begin to cut the aluminum strips . You will be surprised how much aluminum you will use when it comes time to make them for real !

I am trying to install the 602 Fittings that attaches to the fuselage at the 601 bulkhead (where the front main wings attach to the fuselage). The plans call for a NAS 177-6-5 Hi-Shear Rivet with a NAS 179-6 Collar to be installed in the top corner. Is there a suitable substitute everyone has been using here in place of the hi-shear rivet and collar? I have attached some pictures to (hopefully) make it clear what area I am discussing. In the second photo I am pointing to the rivet in question.
