Wing attach bolts

Postby lstinthot » Mon Jan 15, 2018 6:59 pm

I am at the point where I thought I heard people say they rigged their wings. I have a fuselage box and I have wing spars. I am thinking about putting the spars in the fuselage box and through drilling before I finish building the wings. What is the general consensus on this method?

Thanks,
Mike

Hi Mike
If you look at your plans there are a few rigging measurements you will be unable to make if only rigging the spars to the spar box. Setting correct incidence and squareness are 2 things that come to mind.

I am all for drilling the mated spar attach holes to final size before building the wings. But I would hold off the actual rigging to the fuselage until your wings are complete.

So just drill the bolts that hold the main spars in the tunnel then I can rivet the tunnel in place? That is more what I was thinking. I agree we cannot set the squareness and incidence.

The rear parts of the spar box are riveted after rigging. Those parts need to be out of the way, for the initial drilling of the forward vertical fuselage angle.

I show some of the wing rigging in my thread, starting page 77. You will need photobucket embed fix to see the pics.

The spar drilling is before that in the thread.

Thank you for the pictures. I see a little flaw in thinking you can drill the through bolts without the wings built. It will be hard to make them level in this condition. Guess I need to start to assemble the wings.

Thanks again
