Question. How did you put in the brass inserts? Taper one end and then tap, pull out, file the marks, repeat? I have an all brass pipe axe and I want to put in a steel bit. A lot of the ones have the bit dovetailed but I'm worried about a tight fit. The other idea was to square the bit on the brass edge, saw in the middle and drive in a steel wedge, hoping the brass moves enough.
