Suppose I have two parts with holes aligned and I have to install a solid rivet into the "combined" hole.
Clearly the rivet diameter must be slightly smaller than the hole diameter, otherwise it simply won't fit. So I heat this slightly smaller rivet, insert it into the hole and then deform its tail so that the rivet now has two heads and sit properly in place.
Assume I follow all the procedures and best practices.
Does the deformation only affect the tail or does it also make the middle of the rivet expand and fill the gap between the hole walls and the rivet?
In other words, if I wait till the rivet cools down and then grind the rivet head off - will it leave its place easily or will I have to force it out?
