Really sorry - it's set up and ready for me to start work but what was meant to be an 'easy life' http://www.arcforums.com/forums/air/index.php?showtopic=194127) build has broken me.  So help me I'll do the beast - should I still do it here? - but please accept my profuse apologies for the timing.  And regrets that I own another four of what I'm told Canadian folks call 'bear' models...
