The Rivets? I have some thin card... a throw away from our local printer, My wife donated
( after some gentle words and endearments) a wheel with a lot of spikes,I think it is for spacing stiches when doing hand sewing, I place a steel rule along the strip of card and make a line of holes turn it over and you have a line of make believe rivets, the white glue fills the holes made by the points of the wheel. will photgraph the wheel tomorrow and post it. Alternatively find a sprocket from and old clock or something that has gears that suits the spacing you want mount it on a handle after sharping the teeth to make indents on the card. works well on foil or copper sheet as well
