I was a little unhappy when I received this- just another caveat emptor, watch the pics more than the words issue. in any event, it led to a touch of creativity (at least I think so).
The problem:
I tried pressing, heat stress relieving, then silver soldering. Worked fine, initially. Since the Coles neck is Zamak, however, it can't be turned, without opening it for aggressive oxidation, down the road. That left the choice of 1) reaming the barrel, for a looser epoxy-set press fit, or 2) trying to press the neck, as-is, and hope for the best. Looking at the barrel, reaming would have left too little material at the mouth of the barrel- drop it on the counter, and it snaps, sooooo, I tried a straight press. Oh, well.
