Thanks so much, it is a Bitc* of a place. Not exactly the easiest of places is it. Ah well soon as my new circlip pliers set comes they are 12" long so hope this will come off easy. I don't need to re use mine as I have another SwArm that is being powder coated, so need to swap the innards out of one and into the other. <!-- s:thanks: --><img src="{SMILIES_PATH}/thanks.gif" alt=":thanks:" title="Thanks" /><!-- s:thanks: -->
