I believe that apart from forming a tight head, the shank of the rivet should be swelled to fill the hole it passes through. Heating the whole rivet would be essential so bear that in mind if you're trying to use Oxy. The M3 Lee and Grant riveted hulls were squeeze riveted as far as I've been able to find out. And I can speak with personal experience that those rivets swelled.

While not particularly relevant in this thread on Carriers, I'll mention that the holes in the M3 Medium angles seem to be slightly larger than the holes in the plates, so pushing from plate side toward angle side is essential during removal.
