This was my second session of dimpling fuselage parts. I have been doing just the structural piece up to this point. I did have to do 5 holes in the fwd floor panel (F822) that required some creativity to dimple(pictured below), but everything else was easy.
I have the male die in the steel cube and a socket with extension holes the female to dimple 5 holes
Putting the squeezer in the vise works great for dimpling.
