Reading my own message, I see it needs a small correction. I quoted Jim Thompson by saying > Jim Thompson was > right on spot when he asked "Isn't that what twin cylinders are for? I assume that by > lining up their tops as they sit on the index arm, the eye is forced into the correct > angle." Jim must have meant to say "sit on the limb". I took this so much for granted that I did not even notice his slip when I quoted him. And if I am mistaken, he will correct me. Herbert Prinz
