How to dimple these holes?

[tims88]

I'm working on attaching the tail cone to the fuselage and am getting ready to dimple all the holes. I'm not sure how to dimple the holes at the aft most ends of outer baggage floor ribs. The side skins overlap the bottom skin right here. There is a flange on the floor rib that floats above the skins because the tail cone skins and the F-1006B bulkhead fits in the gap between the fuse skins and the flange. I'm pretty sure I followed the plans correctly to get to this point so how have others dimpled this? Thanks.

Either try to separate the skins enough to get the squeezer head in there or I’m pretty sure I just dimpled all 3 together with the pneumatic squeezer.

I believe I used dimple dies that you use with a pop rivet gun and a finish nail. There is a hole in the middle of the dies. I think I bought them from Avery's.
I just saw them the other day. I don't remember what I used them on but I have used them.

But I believe the Pneumatic squeezer will work as Mr. Young suggested.
