Press Fit Pressure
Neil, thanks for the reply. Perhaps the way I stated the problem was unclear. I'm having trouble figuring out the pressure between the tubing and the head. I have no way of judging what the resulting force is due to the press fit.
Thanks for the reply though. It's a weird application as it's an instrument doctors will use to burrow through hard muscle/bone/cartiledge mass. You can really tell a doc to not got about so many ft-lbs when they're using a hand tool. I more or less want to see if a human body could make it slip or not. If so, a redesign may be in order.
