Hello!
Make rivets ( "as" those sold by Archer):
To move and to avoid any destroy for errors I made them on a piece of very thin decal (FFSMC here).
The stencil is attached to a length (top of photo). On the other (bottom) I put a ruler to the stencil is resting on the piece of decal.
Several passages with surfacer mr Hobby ... (9 round trip ...) are required to obtain enough rivets marked.
Stencils on the photo (plastic 0.2 mm) are drilled at 0.3mm drill. The gap between each rivet is 1.5 mm.
We go the full length aero well perpendicular to the stencil. The layer should be smooth so that all rivets have the same height. The smoothest side of the stencil is placed in contact with the piece of decal.
I remove the stencil when finished so they do not stick the stencil:
It works much better with a new and clean stencil. As the plastic melts with the solvent not about cleaning. I pumice to remove the surfacer and give a helping drill into each hole. It is more quickly (believe me) than rewriting a stencil. 5min to clean one in the photo.
Regards
