That is an interesing point I had never considered that looseness could be a problem too, I will look into this further as well as talk to my engineering buddies about their thoghts on the subject.
It's too bad it took this long to begin to get intelligent comment and discussion. Unfortuneately, for most it is too late.
Why bother talking to your engineering buddies about this? Do they work for the auto industry designing this type of stuff? Just because they are an engineer doesn't make them experts. For instance, the mechanical engineer friend of mine who decided to wire his basement because he's an engineer and can do anything. Sure he got it done but he didn't really know what he was doing. My point is, don't pull the "engineering" card because it usually doesn't matter. Another thing that doesn't matter is how many 100's of other forums you participate in. We don't care, and it makes you look bad by saying it, like bragging. What matters is the content of the information you bring to this forum, which if you can't tell isn't being received well.
As for some of your ideas, she they might get the job done for a short time but compare it to using impliment tires on your jeep and then taking it on the highway. They're just tires right? What happens when they fail because they weren't designed for what you're using them for. What the other guys are trying to get across is that when it comes to safety, lifts, that sort of thing, don't scab it together because you don't really know what its failing point will be, so don't try and convince someone that doesn't know any better to do it.
The other thing you're failing to grasp is that your butting heads with guys who either do this for a living and are good at it, or build their stuff to compete and have worked with R&D teams or know people on R&D teams that build some of the stuff that goes on our rigs. I don't know Bill, for instance, but I do know not to argue with him. He knows what he's talking about and has been around the club long enough and has helped a lot of people get their stuff running safely and reliably. So as a forum participant, how can we take what you say as good ideas when you're contradicting the people we either know and trust or know of and trust.
I'd give the tech ideas a rest if I were you. You're not making any friends doing so. Sure, if someone posts a problem and needs help, help away. Just think about your responce first. Like would you do this fix to the vehicle that transports your wife and kids. Or would you do this fix to a vehicle that passes your wife and kids on the road everyday.
The point is you don't have to comment on absolutely every topic, there's no need and it's usually not well received for what ever reason. Not that you shouldn't post at all, just be careful of the advice you try and give.
