Allen,
Thank you very much for the information. This should be of immense help to some of my co-workers that have anxiety attacks when they are selected to do, or participate in fabrication projects. Quite a few times I have observed some of these guy's getting frustrated when trying to figure out how to do the math. Very often I will get them going down the correct path, but even though I know in my own head how to do the computations, I feel that I am not very proficient at explaining the procedures and different methods to others. I have a notebook full of valuable information that yourself and others have shared over the years, and very soon I am going to select the items that I feel would be of the greatest benefit, and spend some time at the copy machine making them each their own booklet. I have found that when some of these people are provided, read, and comprehend information that helps them become successful at whatever they are doing, it gives them a sense of accomplishment and they take a much greater interest in the work they are performing. Thanks again.
