That's what I did. The problem was a combination of too little epoxy and or clamping which squeezed it out so there wasn't enough. The holes were a way to be absolutely sure I wouldn't have to do it a fourth time. Too little epoxy and I could pull the brass off like peeling a banana. Sadly I did have a good bond the first time but had to remove the brass with heat to mend the crack..
