Yesterday I broke out the rivetting tools (4x rivet gun - originally aircraft rivets, rivet cutting pliers) and we installed the early style tarp securing points onto the 2B1 body (and a serious smile onto Bob).
This is another case of the appropriate tools making a job much easier. The rivet cutting pliers shear the rivet while keeping the shank round to fit the workpiece holes. The trigger style used on the rivet gun makes it much easier to do one or two taps on the rivet to get it started before finishing the job.
Bob had recovered every one of the brass securing points he could find on his property - and ended up with exactly the number needed, no spares. Copper flathead rivets were used as per original. Bob had bought a bag of 100 (42 needed for the job) to allow for experimentation, cutting failures, riveting failures and dropped on the floor and lost. In the end these only added up to 6 rivets so a bag of 50 would have been enough but the supplier's
