Dimples not fitting...

I'm having a problem with pieces not fitting properly once I dimple them. This is the horizontal stab. I had everything match drilled and when it was all clecoed together, the pieces fit great.

After disassembling everything, deburring, and then dimpling the skin and ribs, it is now time to rivet them together.

The first rib I am starting with is HS-707. Now that the rib and skin are dimpled, they don't fit together anymore. As you can see from the pic, the rib is clecoed to the skin but since the dimples are not fitting inside each other, the rib is not sitting up against the skin. In the picture below, you can see light between the rib and skin.

What's going on here? I'm using the same dimple dies on the ribs and skin. Is it a problem if there is a little space between parts like this? This is getting kind of frustrating because now none of the pieces I spent two weeks making fit together!!!

Any thoughts??

THanks!!

Totally normal Mark. Cleco's don't have enough pulling power to fully close the gap, but once you start riveting, those skins will come together very nicely. Rivet away!

Yep you're right...closed right up after I riveted it!
