The point I was driving at is that anything that can fail will! It is up to the operator to make the final call as to the safety needs that are at hand and to ensure proper use of the equipment. The fact that one is attempting to do a service that is potentially dangerous calls for an assumed risk.
Any safety equipment is only as good as the operator. If you need a jackstand class, maybe you can find one in the yellow pages <img src="/forums/images/graemlins/smile.gif" alt="" />
I have seen people do all types of wrong methods, me included. It takes a rather abrupt knock in the head to get my attention. It has happened and that is why I strive to pay more attention to how I am setting up to work on anything. Haste makes waste. <img src="/forums/images/graemlins/shocked.gif" alt="" />
If you feel my post was condescending to you, I apologize, it was not meant that way.
I feel safety is a serious issue and that the more prepared someone is, the better.
True, the pro's can get a little complacent. It can cost a lot for that complacency.
