refitting external beads

[wambangers]

hi,
in relation to a similar post the other day,i just wanted to know how you get the external beads back on without breaking them,ive useda rubbermallett but tends to bounce.ive heard that the thor hammers are quite useful,im being cautious here but maybe a sharp tap with plastic faced hammer will do the trick.also is there a special tool to remove??
just to verify im not a burglar looking for hints and tips..mmmmmmm..

regards
