Page 18-05: Flaperon rivet question

When riveting the A-1207 actuator bracket to the A-1203 flaperon spar, depending on how you orient the rivet, either the shop head or the manufactured head will contact the curvature in the bracket (see pic). I don't want to machine a flat surface in the bracket because that would weaken it. I'm at a loss. Any advice will be appreciated. I read the other posts on this, but I still don't know how to deal with the shop head hitting the curvature.

I figured it out. Ground and beveled the flat on the squeezer, then spaced it out with washers.

I wouldn't over think it. If you get a good shop head you should be OK. A good rivet joint is designed to be in shear not tension.
