       I have lots of pics and step by step removal of binding and the back. Then removing the ladder bracing from the top.
       This picture is from today and beginning to put in the scalloped X bracing.  I've worked on this quite a bit so far.

      Oh btw, the work bench was built in the fourties.

This is a 44 year old all mahogany 000, made in the USA by Harmony. I really like it a lot, so I'm willing to invest the time into it.

Looking forward to the final result - IOW, are you happy with the sonic results of the project.

You're both brave and patient to take on something like this!  bowdown

I assume you have decided that the original sound of the guitar is not as good, with the current original bracing pattern, as it could be with your revised bracing pattern?  I also assume you are not concerned about preserving the tone of the guitar as it was originally designed?  In any case, that's a heck of a challenge you have taken on.  It looks like you are well on top of it, Dan.  Once it's done, let us know whether or not it was worth the effort.

I liked the way it sounded. The ladder bracing was not holding the top very well and it was about to break in some areas.
     I'm thinking that the X bracing will sound fine, as well as have better support for the bridge and string tension.

Quite the undertaking. 

My old arch top tenor (Harmony) had the (pressed birch) back come off (dried out and warped all to heck), and one of the top braces came off.  I keep meaning to get to it, but I'm not sure if I'll ever get the back to be the right shape again.  It was my jump from uke to a guitar sized instrument back in 60 something.  I always tuned it dgbe.

A little steam and new braces, with a lot of patience will do it.

Just a view of the X brace. It will be scalloped more and of course more braces etc.

Excellent!  Keep the photos and update coming.  I like that workbench too!  Did it come with the house or did you pick it up from someplace else?

   The work bench and four large power tools were lent to me by a friend of mine. He doesn't use them and knew I'd take care of them. Two band saws, a large drill press and a scroll saw. I need to totally redo my shop now.

Wow what an undertaking.

Why is one x brace longer than the other?

That is the "Danny Asymmetrical Bracing" pattern.

   That's the way it is in the plan I'm using.

I've been working this week due to a heat wave, but  also seeking a decent piece of maple for the bridgeplate and possibly a headstock plate. Finally at Woodcraft I found an excellent piece. The only one that had vertical grain on the end.
    But it also has some flame in it.

So ... are we taking wagers on whether Danny will be using Larrivee-style symmetrical cross braces or Martin-style diagonal braces ... ?

In the picture with the maple board you can see the plan I'm going by. I am making some changes as the braces put tension on the top. Making it strong enough to not have to take it all apart again.
     This may sound like a stretch,  but as the braces are scalloped a little tone tapping may be in order. Being able to tap tune a top would be way cool.

Sorry, but some of the pics got deleted, I'll restore them later.

Finished with the bracing. I did modify it a little and strengthened under the fretboard extension with maple. Tapping the top it sounds great. (But what do I know? )
 I did scallop the braces and clean up inside the top before gluing the back on.



The back bracing is the same,  just hot hide glued up in several places. Tomorrow the back goes on, then the binding and some finish issues.

       (I did take the excess off of the top of the back braces, there is a pic later)

That's cool Danny. I would like to experiment with building, just some ideas of my own. Like another small X brace under the big one. Amongst other things.  +1
