Thanks for the good wishes guys. A lesson to be learnt here, was pressurizing a pipe with air when one of the plugs blew off shooting the pipe off like a rocket. Caught me in the back of the hand real hard, nasty gash & I got to see two of the bones in my hand! I only ever use 40-50psi but obviously it's enough to be wary of. A couple of pins & I'm good to go, although I'm not getting out for a while as they are concerned about the bone getting infected after being exposed. 4 weeks in a half cast, then they say hopefully back to full function after another 2 weeks. Will have to have a serious rethink about fixing dents in pipes, the pittance you get paid for it isn't worth this.
Cheers guys,
K
