Im removing the rivets from my Romanian AKM kit. I pressed out the barrel and simply knocked out the rivets with a punch. They popped right out. Now, onto the rear trunnion. Looking at it, i cant tell if the rivet holes go all the way through the trunnion. So i got out my drill and drill bit set and started off with the smallest bit slowly enlarging it to remove all the pieces of the rivets. My question is, how far do i drill through? I got most if not all of the rivets out on the right side, but do i drill all the way through? How will i re-rivet it back together? How will the rivet smash down on the inside iff i drill it only partially the way through? Or, how will the rivet smash down if i drill all the way through?
