That is cool, but a spinning or bait casting rod is a little different. Not much.
The price of cork however ( the one on the rod I am making $37.), I think I would try NOT to cut it, specially if you are going after the reel seat which is on the end.
However, the boiling water doesn't always work.
It didn't on my Browning and the CORK is what I am trying to save. So in my case I will have to take off the Hook Keep and the winding check to slide half the cork up. Then sand it down and try to connect the two pieces of cork.
As I said, it broke right in half and one side turns freely.
Some things are better left alone, Even though, some feel they know better.
