thank you, Amos, that is helpful. let me add one final problem--
Let us label the strings, 5 to 1, from the drone (5) on up the banjo. Now, let us label the pegs at the end of the neck A, B, C, D, starting from the upper-right and moving clockwise (lower-right, lower-left, upper-left). I know there are a lot of questions here, and every little bit helps. Thanks again.
