Kent, I tried to do some Googling on Bondur prior to posting, but could find nothing related to aluminum alloys. Thanks for explaining that.

Prior to using Dural in airships von Zeppelin's designers used thin plywood.

Thanks for straightening me out on the dimple's use and meaning.

Some of the smoothest riveting I've seen was on the leading edge of a Blanik sailplane wing. The airfoil was a laminar type, so the skin had to be smooth.
Just amazing workmanship. CZ

Default Produce from plane.

No science, production from leftovers
Imagine living at that time in Germany. Everything is broken, but the remains of the Messerschmidt and Focke wulf aircraft, wrestling vehicles with Wv engine and axles are is here. And you have a small barn, a wooden log, plenty of time and a lot of will. Even in a very distant dream you will not be confident that your creation will come to a museum in Hamburg. It is very nicely made, but it is a product in which many "despair of the time history" are added in addition to the work.

Be aware that some of those are what are called icebox rivets. Which means they are heat soaked and then put in a cold box until driven. Usually within a few hours. Then then harden at room temperature.

That is so exactly the vibe I'm trying to achieve with my project. Although probably more Francophile in feel! And a rather simpler body.

But...I'm inspired!

Re #13, Captn Zap.

You'd be surprised what a little "massaging" can do to smooth out the depression that frequently appears around a rivet.

Finish off by placing a rather heavy bucking bar behind the shop head and lightly striking the outside, centered on the rivet, of course, with a fresh (soft) rubber mallet. It raises the depression generated by the riveting.

Viola, smooth, riveted skins!
