I have an old ( from the 5o's?) bamboo rod in great shape except the cork grip is completely gone.

My question, and I am new to this, is what would be the best way to put a grip on the rod? If I could get the rear rear seat off I could then ream out a new grip and slide it into place? Is it possible, using heat? to get the rear reel seat off the rod without destroying the seat and or the rod?
