    A belated 'Marvelous!, I just picked up an Otis-King cylindrical slide rule. It's very elegant, as yours is, One problem. The scale has detached from the cylinder and when pressed back on, does not meet itself, by about .06 in. Of course, this renders it useless as a calculator. I haven't read the entire thread of your post, but could you tell me what kind of glue you used and any suggestion for stretching the scale (humidity has been suggested. I haven't tried it yet)

    My physics teacher gave me this problem: Wrap a string around the Earth, and pull it snug. Now, add an inch to the length of the string. How far off the surface will it stand?(assume it's symmetric)
