a bush, eh?

I'm gonna say this... get a whoopin', but here it goes.
In the machining world, there is the expertise of art as well as science. What separates the two is the experience of the person doing the work. Two maxims we use in mold making industry are "if you can hold it, you can cut it" and "dont cut it to the size you want it to be, but the size you want it to become". The first emphasizing that fixturing is the key to successful metal cutting operations, even when the operation is simple. You cannot add stress in holding the object, and in cases where you cannot adequately hold the workpiece, then you have to do your best and make repeated very light cuts. The second being, that not only do parts throw from the mold in sizes that are different from the mold, but the mold itself will change as soon as you use it. You cut it to the size it will be under use, and also, as an extension of that idea, to the size that will throw correct parts in a production environment.
In my own specialty of electronic and applied technology service, I've hired four ex-military men. No personal offense, but I've had to depro, devo and retrain each of them. I hired them because the test I gave them required original thinking, not having black and white, right or wrong answers. They all had the core of a good employee - a brain, and the ability to use it, think on their feet as well. Yes, they take the test standing up, and its timed. For every thinker, there were 20 or more that were what I call "script kiddies", who, like rats, eventually learned their way through a particular maze, but who had no non-military working environment skills whatsoever. I short, I could have given a crap about what they did, learned or became in the military. What I wanted to see was what they could bring to me that would produce results with my customers, get the job done, adapt to a highly fluid working condition, and attitude, attitude, attitude.
Dont expect to start anyplace but on the bottom end. Do expect, that with hard work, proper communication skills, and perseverance, and proper attitude, you can work your way up to a better position.
