john, how right you are, i once pulled off the vac hose and it did jump up and stuck to my cheek, me and my helper laughted about it, it looked funny at the time but after a few minutes i realised what could have been, as you say i had this vision of it pulling the eye out, it scared me enough that now i am a bit over cautious about vac hose removal,

ps hope you get better soon richie
