Straightening out an outboard tip rib(e-903) RV-10

Part came about as straight as my garden hose. Any ideas about how best to straighten this part.

Thanks in advance.

Bent

I recall mine not laying flat on the bench. However by the time you cleco the two end ribs back to back and put the end skin on, it all seemed to straighten out.

Or are you talking about the rib flange? That has some wicked bends in it to work around the layers of aluminum you end up with where the two skins and front spar meet.
