Thanks for sending that Andy.I ordered one from Apex over 3 weeks ago.I have phoned them twice since and it still hasn't turned up.I have my cylinder back which has been nikasiled and was waiting for the valve kit to turn up.The reason behind it all is that I ......yes you have guessed it tried to undo a left hand thread the wrong way.Hence I sheared the spindle.However at least I know for next time.I clicked on PAYPAL on the homepage to make a donation to the site and it came up error.Am I doing anything wrong
