The standard air pressure in UK air driven tools is 50 psi. I worked on
aircraft for 22 years using it, oddly enough, so I do know what I am
talking about. The air-driven tools were of American manufacture by the
way.

The list is read by many people, are you saying we should not put
warnings in? Ofcourse air lines are useful, I do not quite get the point
you are trying to make. I was advising someone whose engineering
knowledge was not as great as most. Airlines can kill, do you find that
strange? I quoted to you a recent fatal accident, ( if it can be called
an accident.) Air can be forced under the skin at as lower pressures as
10psi. Air in an artery entering the heart or brain is often fatal.

To check a metal bar or a tube, it is engineering practice to roll it on
a surface plate, or a plate-glass sheet. This is a quick way of seeing
if it has a bow or bend in it. If you like, you can also put the
push-rod into a lathe, in a chuck and a centre, and use a DTI to measure
its run out. A bent push rod can be sprung out of its position at high
rpm, which could wreck an engine. Are you saying I should not have
mentioned this check? If you have a better idea to check them, let us
all see it please.

I was under the impression the list existed to HELP people, and I try
to do just that. If you have a better method of doing things, then say
so. We would all like to hear them.
