Good news - I put a small bit of "Knot sense" on the male end and it tightened it enough for the larger female to fit fairly tight, so I'll just find a rough piece to mount that female on and I should be set without chopping up the old butt. If it loosens up later, I can add a little more knot sense on the fly - that's great stuff! I use it for mending my garden hose, sewer hose on the RV, and lots of stuff.
