I'm New Here
What are the skin thicknesses on an RV-8? I'm finally wanting to start my project (been sitting for years...). But before I start, I would like to practice riveting on scrap. Are all the skins 2024-T3? Any help from you experts is greatly appreciated

Skins

They range from .025, .032, .040 . There are some sub structures that are extruded or plate that are .125 .
There are also some sandwiches that are 3 layers thick ….
