Instead of double/triple-rowing the joint rivets why not use a couple of 
small stainless screws/bolts with appropriate lock washers and nuts or 
nylock nuts?     As matter of fact if there is a need to double/triple-row 
the rivets to prevent potential mechanical problems maybe rivets are not 
the best way to secure the joints - just use screws/bolts?   I know there 
are  many cases where pop-rivets are working just fine but to me they've 
always seemed kind of a dubious method to make secure reliable long-lived 
mechanical joints.
