Flush rivet option poll

[142YX]

Thanks for the response guys, i do appreciate it.

I forgot to lower my air compressor pressure when i did my leading edge, and this probably contributed to the failure rate.. but i can honestly say that i have tried just what you have both described in the past as still experienced a high failure rate. Using Sonex's simple dimple die, i found that the hole was way to big if i used a #30 before dimpling. I ended up using a #32 simply because it was the smallest hole i could make and still jam a cleco into, and fit the simple dimple die nail through, and i was still really disappointed in how large the holes came out post dimpling (50% of clecos will just pop out of the final hole). I think when i do my other leading edge, i may try to find a smaller nail (which will probably surely break on me) or make some kind of custom nail so that i can dimple through a #40 hole and then upsize and painstakingly de-burr post dimple. These CCC-4# rivets really have been the biggest annoyance to me overall from this entire build.

There is a good article on this subject on the sonexaus website:

It adresses the issue of nail sizes and provides tricks for how to still make the cleco's usable
