Scotty shows what you should avoid doing when fixing your own car so you don't damage your car or yourself. 50 years later, Scotty is still in one piece, and you can do the same with a few simple pieces of advice.
I've also learned the hard way to steer clear of 12 point wrenches/sockets. Just way too easy to strip nut/bolts and I've killed more than my fair share of them. I gave away everything 12 point and bought all 6 point only. It's not always as fast/easy as 12 point but I haven't stripped anything yet with 6 point. Need to pay much more attention to the torque though. :-D
dont mess with texas
Great Post on safety Scotty! Protect the "tools" God gave you!
