My pair of clubs have the knobs attached with glue and a pin.
The Ball has a section of dowel sticking out of it - I'm not sure if it was made like this or glued in, because I don't really want to try taking it off.
The bit of dowel is pushed into the body of the club and glued in, then the whole lot is drilled through and a pin is glued into place running through one side of the club's body, through the glued in bit of handle, then out through the other side of the club body.
The pin's then cut off flush with the club body.
Hmm, that might be a bit hard to follow. If you want, I'll give it another go, with pictures that should show what I'm blathering on about much better than my words can.
