That's the answer I got as well. My starting equation was: 1/3X + 1/4X + 8 = X (where X is the total length of the bolt) -- JF On Mon, Sep 20, 2010 at 7:13 PM, William Monroe <bill at a440piano.net> wrote: > Paul, > > I believe Bruce got it.

That leaves 5/12th of gray. 5/12 = 8yds, so 1/12 = 8/5 (or > 1.6 yds). So if 1/12 is 1.6yds, 12/12 or 1 (the whole thing) is 12 * 1.6 = > 19.2 yds. > > William R.
