How do you put on lacrosse head that's too big for the shaft?
If the head fits then you just need an electric drill and put
the head on. Once you have the head on, drill a screw into the
shaft through the hole while applying pressure on the drill. If the
head does not fit, Then put a pot of water on the stove to boil.
Once it is boiling, dip the bottom of the head into the boiling
water for about 8 seconds and then squeeze it onto the shaft. This
worked for me with a metal shaft so you could try it with a wooden
shaft. Instead of all this you could go to your local lacrosse shop
and ask them to do it but it will cost you $$$.
