I started today to rivet the fuselage firewall. It is good to begin to rivet.
But I cannot find on the plans what rivets to use to rivet the K1000-4 nutplates to the firewall that holds the doubler for the fuel pump.
I cannot think that I should countersink them and then use a AD426-3-?
What is the proper rivet please.
Thanks
Dave

Countersink the reinforcement plate for all of those rivets. For the rivets that hold the nut plates I'd go with a 3-4 or a 3-4.5

Dave,
A very good option for riveting nutplates on is to use 3/32" NAS 1097 rivets, commonly called "oops rivets". This avoids any dimpling of either the skin or the underlying part, or the nutplates, since the parts only need a slight countersink for the rivets to fit flush. The flush heads on these rivets are smaller than the normal 426 rivets and they only need a slight countersink, but the rivets that hold nutplates on aren't structural. Their only purpose is to hold the nutplate on. You can do the small countersinks with your deburring tool. The smaller rivet heads really look nice. I've used them throughout the project for installing nutplates, etc.
I don't have a shot handy of a nutplate installation, but here's a shot of my rudder cable fairing, installed with these rivets. You can see how much smaller they look compared to the normal 426 rivets also in the picture. It's easier and less work, in my opinion, and works great.
