I just noticed something on the very detailed drawings, that may have some interst to those familiar with drafting and interpreting drawings. Unfortunately I cannot remember some of the drafting terms, so please bear with me. I refer to the post of ATTIQS dated 3-14-07. The first drawing shows a front view, a side view and a bottom view. Note that the side view shows the LEFT side of the front view, and that the bottom view shows the TOP view of the front view. In Europe the projection of the three basic drafting views ) front, side and top) is opposite to the convention used in the United States. On a simple drawing like shown this will not be noticed by most people and should not be a problem. On a more complex drawing you may get the feeling that your eyes are playing tricks on you because the drawing seems to be laterally reversing in your brain. Once you understand the two conventions you will have no problem. One convention, I believe, is called left-hand projection, and the other is called, I believe, right-hand projection.
