I want to take a few inches off the butt of a rod with an over-long handle. It's no problem to cut a section out and spigot the end piece back on. but when I've done this before, I've ended up with a rather ugly join as the faces are not perfectly flat, probably because I'm not doing a good job of hacksawing through the combination of soft cork and hard blank. So I'm restraining my urge to saw and asking, can anyone suggest a good way to go about it?
