<p>The lowered non-original bridge showing in the pictures has been again modified. I've added two rosewood strips to restore it to the original height. This holds the saddle properly for now as I hunt for a new bridge. Looking for a replacement that is similar to original or something that catches my eye. But since it's my guitar, I can wait for now. The guitar has really begun to open up again after being played for 3 weeks as a practice loaner to a visiting classical student. I'm happy with my results for now. </p>

<p>I could be wrong, but if that is that the proposed height of the saddle. I have seen bridges fail due to the saddle being too high above the bridge. this can cause a lot of forwards torque at the top of the saddle, due to a steep back angle pushing and the strings pulling the saddle forward. This can cause a lean of the saddle in a shallow slot, or worse pushing the front of the bridge out, as in my photo.</p>
<p>Also, check if the tie-block s strong enough to handle a steep break angle, if there is one, not much meat above those string holes.</p>
<p>But you will be the best judge, you have the guitar in front of you.</p>

<p></p>
<p>I have not addressed the slight up bow in the neck yet. I'm thinking of mounting the neck, string it up and see how or if the bow inhibits the playing. </p>
<p></p>
<p>From that, IF needed, look at possibly heating the neck and clamping the neck straight. Or removing the fingerboard and installing a carbon fiber bar. That I have never attempted. But I have replaced truss rods before. Taking that slight bow out would flatten down that rise between fret 1-7. Raising the angle a bit more. </p>

<p>Mark, Taffy and Chris thanks for your insights.</p>
<p></p>
<p>The neck is out now. I did start with simply syringing in boiling water. But only the bass side would release, so I went to steam. The cedar top / top of the neck block glue loosened. I can't say if it was loose before I applied heat to the fingerboard extension or steam to the dovetail. Didn't see anything in the pre pictures I took, but didn't attempt a feeler gauge test.

<p>The neck is out now. I did start with simply syringing in boiling water. But only the bass side would release, so I went to steam. The cedar top / top of the neck block glue loosened. I can't say if it was loose before I applied heat to the fingerboard extension or steam to the dovetail. Didn't see anything in the pre pictures I took, but didn't attempt a feeler gauge test. There are 2 cracks is the top, each about 3/16 in under the fingerboard, that go back from the dovetail pocket to the first of the two top braces between the neck block and the sound hole. I didn't find any moisture getting into the box while using the syringe. But as I used steam I could feel it accumulating. I believe that the 2 cracks somehow were a result of my working the stubborn treble side of the dovetail. The neck and body have had time to completely dry now. I've re-glued the top to the neck block. I repaired the wood binding that came a little loose at the ends at pocket. Made a spruce patch to run cross grain to fit under the 2 cracks to stabilize that area. That went in Saturday morning. I want the neck block area stabilized before I start dialing in the re-set.</p>
<p></p>
<p>Mark, I believe there has not been any movement in the top after the extension was released. The top was flat before, and remains flat now. The neck block seems solidly attached. I have taken a .002 feeler gauge and cannot get any entry along any seam around the neck block at the dovetail or inside. </p>
<p></p>
<p>Taffy, Thanks for the pictures, but there was no evidence that the board end had moved closer to the sound hole. No lip I could catch a fingernail or razor blade on to detect. No top failure and slippage like your picture.</p>
<p></p>
<p>Chris, I don't feel any protruding fret ends. I have witnessed a number of fret boards shrinking a little when I've removed them completely to replace truss rods. So I'm aware of that possibility.</p>
<p></p>
<p>What I think is I needed to be a little more observant and inspect these things more before ever starting to disassemble, It still wouldn't change what happened when the fingerboard was released. But I could answer these questions. Bottom line is I'm guessing what happened. </p>
<p></p>
<p>But from this point forward it becomes two issues, a definite neck re-set, and to evaluate if I need to and how to address rise in the neck/fingerboard from possible slippage. Maybe time for me to put in my first carbon fiber rod support. </p>
<p></p>

<p>Hi John,</p>
<p>I have been recently trying to fine tune my neck setting skills (I've done about 40 so far and the results can vary depending significantly based on a range of <span style="text-decoration: underline;">very</span> minute issues). I've come to believe that the fingerboard extension plays very important role to a proper neck angle. On instruments where the fingerboard extension has come loose, the neck seems to move forward. I conclude this is because the fingerboard acts as an anchor to help stabilize the neck. I would agree with Taffy's suggestion that the fingerboard may have slipped forward if the guitar got hot, particularly if it had steel stings on it, but I also wonder about another possibility. </p>
<p>If the fingerboard shrank over time (as many do judging from the number of instruments that have frets extending out of the edge of the fingerboard), I wonder of it might actually be pulling the neck forward creating the issue you describe. The fact that the neck angle changes when you release the fingerboard extension, particularly since it is not under tension, seems like a pretty clear indicator that it is somehow part of the problem. </p>

<p>Hi John, did you work out a solution? What you outlined appears to be the case. However, in photo one, the light under the straightedge appears to ramp up at the front of the bridge, indicating a raised top.</p>
<p>In photo 2 the line of reflections also appears to indicate a radius in the top, behind the bridge. Some nylon/classical guitars have flat tops.</p>

<p>Were there any signs that the fingerboard had moved towards the soundhole? In a recent repair I did the neck sides and neck block had tilted towards the bridge by 2mm and changed the shape of the soundhole. The neck could not be reset, due to the building style, so it was a massive challenging repair. The action was at 8mm at the 12th.</p>
<p>I have photos but I don't think they would help, in this case.</p>

<p>I pulled the 13th fret and drilled forward into the dovetail pocket last night. Set up to syringe in boiling water and see if it would soften the glue and remove the neck. But I looked again at the angle, and I think it decreased again about 1/64 to about 1/32. So hard to line up a back ruler, and align my line of sight to properly read the measurement.</p>

<p>I pulled the 13th fret and drilled forward into the dovetail pocket last night. Set up to syringe in boiling water and see if it would soften the glue and remove the neck.

<p></p>
<p>More background on the guitar. When I acquired it back in 2012 the bridge was missing. I did not have any background information from the previous owner. A very clean bridge footprint. Looking closely at the tuner rollers last night, it may have been strung up a some point with steel strings. Slight impressions coming out of the hole in the plastic rollers in strings 1-4.</p>
<p></p>
<p>The neck has a slight upward bow. No truss rod or any internal support. Sitting a ruler across the 1st to 12th fret I find a gap that increases up to a max of .009 over the 6th and 7th fret and then decreases to the 12th. String action at the 12th before loosening the fingerboard extension was high at 1/4-3/8 if I remember correctly a few years ago before I removed the strings. I did not re-string it and measure it before starting this re-set.</p>
<p></p>
<p>My guess for today,</p>
<p></p>
<p>Now for an episode of GSI, Guitar Situation Investigation. Today's show "Blame and Explain This Dilemma". </p>
<p></p>
<p>Could this guitar have been exposed to a hot car or room/attic a few times? Enough to allow the neck/fingerboard/top glue to soften and move under string (maybe steel strings ) tension, cool and re-harden. Then eventually the bridge glue failed and it came off. Tension now removed, and the re-hardened glue holds the neck and fingerboard in this new position. </p>
<p></p>
<p>After loosening the fingerboard extension, could I have relieved some of that applied tension behind the 12th fret and the soundhole? Allowing some flexing back into a relaxed condition and decreasing the neck angle?</p>
<p></p>
<p>But the bow in the neck most likely will need to be addressed at some point. </p>
<p></p>
<p>Opinions? Theories? Insights?</p>
<p></p>
<p>Thanks in advance.</p>
