I believe it's the aluminum "shim" there in the pic that is providing the backup against pop rivet.

I agree, I guess I was just thinking out loud for any new builders / lurkers.

Great Idea,
after building my left flap and using a 1097 oops rivet for the rib that attaches the nut plate, I found that using an AN470 3-4 worked out just fine with no problems, You just want to rivet that one first so that you clear the doubler.

You are both absolutely right.

On the left is my first try with just the washers...yuk...very ugly and was summarily drilled out and replaced. The right rivet was with the use of the aluminum spacer. The final product looks indistinguishable from other pulled rivets set without the washer get-up.

I also tried a spacer made out of hard wood prior to this. It split.

I am sure someone with a small milling machine or lathe will make a perfect bushing of some type that will put my washer rig to shame... but for me it was field-expedient, cheap, effective...right up my alley.

Someone once told me that "if it is a dumb idea...and it works...it is not a dumb idea."

Feel free to use my "dumb idea."

I've cut down and ground down my cheap pop rivet tool so much that I'm amazed it's still able to hold itself together in one piece. Building this plane has given me new skills in making and reshaping tools of all sorts.

I am right there with you John. After I ground down my cheapo rivet puller I was amazed that it actually still worked!
