Hey BugPope,
I use metal headed sewing pins for my rivets. Here's a couple of pictures from one of my Landships showing my 'pin' rivet technique from the outside and inside. I pre drill a hole where the rivet goes put a drop of supaglue on the pin shaft and slide it into place (cleaning off any excess supaglue straight away). If its an enclosed section like the turret of the Pulp Jalopy I don't trim the pin shafts but for the Landship example I did to allow room for wheels...


Cheers
