wing ajustement

Eccentric bushings? I always thought they were a cool idea on Cessna wings, but what must be done to the wing attach bracket? It has to be drilled out quite oversized to make these work?

Also, my eyes are watering.

Looks like they've welded on some huge doublers. I hope it's strong enough...

So how do you stop the wings moving around when using a rotating eccentric bushing like this?

Are the wings held in by pressure, not unlike the struts on your vehicle, where everything is squeezed together? Or does just the bolt do all the work?

All fittings are pinned connections from an engineering standpoint, so they only transfer linear forces (but not torque).
So all four fittings will experience a lot of up/down forces and axial force in-line with direction of travel.
As well as that, the rear fittings are being compressed into the fuselage, and the front ones are in tension, pulling away from the fuse.

The bolt does all the work, apart from the axial force in-line with the direction of travel.
