Yep, yep, yep ! That's for sure, Pete. It's just like removing the head from a golf club. A little torch (heat) to the shaft, the heat runs up the shaft to the glue, loosens it, and if you are applying some rotational pressure to the club head, eventually, very shortly, it will pop loose and come off in your hand.
Of course, that is assuming that the dice on Wayne's shaft, is glued. If not, the vice and a little elbow power, might just do the trick. I've never used glue, of any kind, on any of my kite stakes. I just drill the hole in the golf ball, slightly (1/32") smaller than the rod, and then I just drive the ball onto the shaft with a rubber mallet. Once the ball is on the shaft, I then sharpen the other end on a grinding wheel. Never had one to come off, or twist on the shaft, either............
