I have 1/8 x1/4" knurled solid
copper rivets. I would like to use these to locate the front and back heads of a 1-1/2" diameter copper boiler.
I am thinking 3 rivets 120 ° apart . The flanges will be hard soldered . I plan to flux the front and backheads , then drill the rivet holes and flux them too. I have not used rivets . Do the rivets need to be backed up with a solid piece of steel and then hammered. This can be done on one end only. I have a 12" x 1-1/4" steel round which I can hold in a vice. The boiler barrel can slide over the round.
Is this necessary with knurled copper rivets. Also should the solid copper rivets be annealed?
