Thank you guys!
First try with "metallic scotch tape":
The metallic scotch tape must be sanded to become very fine before being cut. Riveting is made before cutting.
the first plate was destroyed when I wanted to fabricate roundness. I did it again four times, glued together four times and sanded glue four times...
Finally I glued it by using plastic band to fabricate tabs (in black "dymo") as wedge.
I would like to paint wings inferior. She will be an American spad. I read that underside was grey, or without painting nobody seem to know (as always).
I read the article on the 5 French tones:
French 5 Color chips from Methune Handbook
What is about MisterKit paint ??
