Wings clamped together outside airframe

Main spars drilled to full size using step drills. Easy to maintain control and direction with wings outside airframe.

Fullsize drillbit poking through

After carefully reaming to size, the bolts fit perfectly

Rear spar clecoed in place. This ensures correct distance on the rear spar carry through assembly will be set as the main sparts are clamped together.

To siplify alignment, we kept the rear spars holes at 40 size with this exercise in mind.

We made two fullsize OD / 3/16" ID bushings and inserted them into the main spars. Then we drilled the fwd fuselage angles and spar tunnel

Wing rigging sequence complete. The wings are fixed to the fuselage the way they should for the first time.

The rigging of wings to fuselage is a critical part of the build process. Ever since we first started the project, this building step has been on our mind, and we ended up doing it slightly different than called for in the plans.

1) First we mated the wings and full size drilled the main spar outside of the fuselage. This made it easier to keep everything still and properly clamped together while drilling. It also made it easier to maintain direction while drilling, having everything outside the fuselage.

2) With the main spars clamped together, the distance between the to rear spars were set, and correct lineup and initial drilling of the rear spar carry through assembly, could be done.

3) Once lined up inside the fuselage, we pilot drilled the fuselage side angles and spar tunnel assembly to 3/16" by using bushings inside the main spar for guiding. Everything were then removed from the fuselage, and the side angles and spar tunnel assembly were full size drilled in a drillpress.

We carefully reamed the main spar and the fuselage angles/spar tunnel, once assembled with holes to full size. We're extremely happy with the fit and accuracy of this critical assembly

Hej Rune og tack for raskt svar!
Låter gott med er framfart og jag hoppas att under nästkommande år få sålt min Murphy Rebel 1650 så att Sonexorojektet får lite ekonomiskt bränsle.. ;)
Håper å få återkomma med litt spörsmål framöver om ok?
All the Best

Hei Ivan, det går fremover med prosjektet. Vi har hatt tre oppstarter med motoren og etter mye plunder med elektrisk og kjøling fungerer det nå bra.

Hello Folkens,
Hur går det med bygget?
Tror jag följer ert exempel för min Sonex och avstår från D-motorn....
Blue Skies!
