*****************************************
This is my guitar, given to me as a gift from a good friend.
So I will do what is needed to make it play well, in any fashion I see fit.
Many "non traditional" methods and repair compounds will be used to do so.


I want it to be able to play as well as possible, considering the condition in which it came to me.
And I want that to happen in a reasonable amount of time.
This is not a lesson is Trad repair, I want to be clear about that.
Not everything is worth that much time/effort/expense.
Now that we are clear on all of that...


There is also the REMOTE possibility, that it was an "employee made" instrument, having no FON/Serial Number.

INITIAL PICS
No perghead overlay, had stones or something.
Small cracking over neck block.
Decent steam job to remove neck.
Some have cupping from being open a long time.
Rectangle bridge was 1930.
Numerous back cracks.
Repair Sequence #1
Back Removal
Since it has already been removed in the past, and since the top is x braced, this is the most prudent entry point to save the top which is in far better condition.

So some gentle heat and off we go.
The piece of masking tape repair, did not.
What we really have, with no braces.
Shaping and filling and leveling.
All back in place.
Adding side markers-3/32"
Repaired one brace, now for some cleats.
Dust and CA for missing wood by bridge holes.
Several crude repairs were done in the past
broken and missing braces, crude maple repair.
Now to make it all one again.
Center wood removed, ready for new sections.
Back semi-leveled.
Back tio the finish that it had previously.
Kerfing repaired. L-0 bracing in diagram.
Rib repairs on the bass side, holding well.
Alot of damaged kerfing from non-trad glue usage.
Mahogany dust and CA for filler.
Measuring the cuts.
New peghead overlay installed.
All braces re-sealed
