Over the last 5 days I have been working on metal covers for books. Rivets are a design feature of the covers. In all I have made 16 sets of covers which entailed hand setting 410 copper rivets.
My copper rivets start life as small (1.5mm in diameter and about 20mm long) pure copper nails I purchased in Japan. As part of the riveting process these nails are: set, cut to size, domed and hammered flush with the surface.
Following are some photos of the process and the final products in the rough.

A trick I learnt - holding the pieces of metal together with double sided tape; and using the clamp to make sure of a really good connection. Then there is no need for clamps etc when centre punching, drill ing and riveting.

Casualties - I used about 25 1.5mm metal bits in drilling the holes for the rivets. The stainless steel was very hard and either busted the bits (after as little as 3 holes) or wore them out (maximum out of a bit was 24 holes). I used a drill press for the job to keep the revs down and the pressure gentle and even.

I achieved my goal of getting the riveting done by FRiday. Now that deserves a glass of red.
