<p>John i'm sorry for the delay , i must be the busiest luthier in Australia , Ive noticed that the back is wider than the top , its 14 1/8" on top and 14 3/8 " on back , a straight edge across the widest point gives a 1/4 "gap each side . I'll let you work that out . First back brace is 5/8 in centre , 2nd same , 3rd 9/16 , and 4th 9/16 in centre . Top 1st is 5/8 2nd 9/16 , 3 & 4 are 9/16". This is the model with plastic bridge which was replaced when I bought it in 86 with an ebony copy .…</p>

<p>Len,</p>
<p>Could you take a few pictures and estimate height of the back braces on your guitar. I can get the width from the glue footprint on the back.</p>
<p>I have:</p>
<p>the first brace behind the neck block</p>
<p>missing the second</p>
<p>have the third</p>
<p>and missing the fourth.</p>
<p>I'm guessing 1,2,3 will have the same profile. But the 4th brace is an unknown. It's wider by the glue footprint, but I have no idea of the profile.</p>
<p>Thanks in…</p>

<p>Thanks! </p>
<p>I'm going to take a few days and make these two tools.</p>
<p>Now, I'm going to hunt up a few pictures of the missing back braces to get their profiles. </p>
<p>For the top missing braces I'll duplicate height and width and the squared off tops like the ones still attached.</p>
<p></p>
<p>Thanks again.</p>

<p>Hi John,</p>
<p>not being any good at maths other than adding and subtraction, I use this idea I devised to help me. See the photos.</p>
<p>The following math I don’t understand, but muddle through it.</p>
<p>To calculate the radius:</p>
<p>Once you know the width and the height, the formula for the radius is…….</p>
<p>H/2 + W2/8H</p>
<p>Where W is the distance across the guitar top, Width of the base of the arc</p>
<p>H is the height, measured at the middle of the arc’s base.</p>
<p>Hope…</p>

<p>Hope this helps if you can understand it.</p>
<p>This will find the radius of the top, but keep in mind that it may not be the makers' original built-in radius as these things change over time.</p>

<p>I'm not sure. I'm working on that with my son. Conquer the world through math. But I'm looking for a confirmation or consensus information before going forward.</p>
