Sorry to ask a simple question, but what causes a rattle in a head
Unfortunatly the answer is not quite as simple. The rattle could be from a stray piece of epoxy that has fallen into the head or something has broken free inside the head.
Best way to fix it is simpler. Remove the head, see if there is a plastic plug in the bottom of the hosel hole. If not that could be what is rattling around! With head off the shaft shake it and see if the "rattle" falls out. You can use mouse glue (messy) or easier method is to stuff the head with knitting yarn or cotton or foam it if you can find the foam (hard to find because it has something in it that "hurt" the ozone layer?).
Once the head is "stuffed" and no rattle noise is detected you can reassemble the club. BUT FIRST PUNCH A PLASTIC DISK TO COVER THE HOLE IN THE BOTTOM OF THE HOSEL.. You can punch this disk out of a coffee can lid or something similar. Disk should fit snug and be pressed to the bottom of the hosel.
