Rivets in copper to join soldered head through brass sheet then leather

Hi Randy,
Thanks for the pics! nice ideas for shooters.
Now the rivets you should look at in copper are brake shoe rivets,
there made to be set with a punch and are hollow ended Plenty strong
enough for the application, also with a countersunk head. As your
rivetting through leather as well, with a copper backing washer, that
brake shoe type is the one to try. Brass will be much to hard where
leather is involved.
Theres something wrong with the G s/ware so im writing this as an email.
Confirm you get it.
