seven-thirty-seconds

Updated: May 15, 2025

What I find a nice medium is seven-thirty-seconds of an inch from the bottom of one slot to another. Take the compass and divide to seven-thirty-seconds of an inch and press one point at G, D, A, E, allowing a fair margin at both sides of the ebony, not above, say one-eighth of an inch good.
