Craig, this style handle with the long ferrules, IF I REMEMBER CORRECTLY (mine are packed away and I can't get at them currently..),,,, but there is one style that had a smooth post (no screw threads).... which required gentle rotation... let me see if I have any pictures in my huge picture files... 'somewhere' on my computer...

I have a tall plastic bucket that I set the paddles in, handles down, and then I use KROIL around the top of the ferrule all the way around......
