Ok guys thanks for the replies, I will let you know how it tuns out, as for touching machines with out the person there, I know what you mean, I restore, and work on old cars as another hobby, and have run into the same problem, I have even helped people fix one problem and then they get mad because something else broke afterwards( weeks, days later), and said they never had a problem until I told the to change something and that my advice broke the car! I have learned in certain situations it is sometime best to keep you mouth shut, and your hands to yourself! LOL! Sometimes it doesn't pay to be a nice guy, unless you know the person and how they are going to react.
