Was out fishing and on a hard cast I felt the cork tear...I’m wondering if this is something I can fix myself and also is there anything I can use to prevent this from happening on my other corks handles 

 This is the butt end of the rod if you can’t tel from the picture 

I think it was a fluke. I wouldn’t worry about other rods. You can inject epoxy into the cracks and clamp them with heavy rubber bands. Clean up with denatured alcohol 

I will only add that clean up has to be done before the epoxy hardens or it will be a tough, precise, sanding job.

Ok thanks if I decide to replace the cork butt instead of repairing it, could I just remove the old one and slide a new one on with some epoxy ?

Yes, but not as easy.  Carefully remove the old one.  For the new one I usually bore the hole using a drill press, but it's easy even with a drill press to not get the hole in parallel to the axis of the butt.  You also want to mark the drill or engage the stop so you don't drill through.  

 

The aluminum winding check presents a complication, too.  You don't want to damage that in removing the old butt.  If it comes loose in getting the old one off be sure to put epoxy on the bore and the surface that touches the cork.

 

I would simply repair the one you have to avoid any complications that might come up with a replacement process.

Ok thanks for the info , I have a lathe I can bore it out to a nice slip fit , do I epoxy the new one in place ?

Yes, put paste epoxy in the bore and on the blank.  It will squeeze out, but won't run like liquid.  Use generous alcohol to clean up while it's still not cured.  You will want to load it against the aluminum winding check to prevent a gap from forming, not much, but just to keep it tight against the check.  You can cobble something up for that.  Maybe rubber bands as earlier suggested.

Ok thanks again for the help
