Decided to purchase a set of Cleveland Tool Structural Dimple Dies to see how they work since the Practice kit is a great place to try some new things!
Got the Ribs deburred and match drilled. Used my standard dimple set to dimple the skins, then switched to the new structural dimples to dimple the ribs. Wouldn’t you know the structural dimples worked as advertised. (Sorry, in my excitement I didn’t take pictures!)
On to back-riveting, went ahead and put the rivets in the skins and taped them down. Flipped the piece over and added the ribs. Back-riveted 2-3 rivets before I had to call it a night as I was making a bit too much noise at 9pm. Oh well, I’m all set up and ready to start again on Friday afternoon. I have a feeling I’ll have the control surface completed by the end of the weekend.
